I take notes, draw sketches and work on outlines for my other ideas, but avoid jumping into the full thing. I tried working on multiple projects at once, but it never worked: I'd either up working on just one thing and scrapping the other or ended up scrapping both to do something else entirely 
so nowadays I just tend to focus my energy on the "big" project and just work on other things whenever I have some free time/inspiration/whatever.
It really depends on your goal!
If you’re trying to go commercial and build and audience/make money it’s worth assessing the ideas side by side and even getting feedback from others on which concept excites them more. (Depending on how far along you are with the original idea… you don’t want to become a chronic non-completer…) If you’re early in your career it’s probably more important to build up your completed work portfolio and build reader trust by completing something, especially if you’ve already started posting it.
If you’re writing/drawing for fun then you can kind of do whatever you want that’ll be most enjoyable for you! If you’re super excited about the new idea then go for it!
In terms of strategies to avoid the distraction of new ideas… I absolutely write them down as others said. I’ll even allow myself to think about them, add additional notes, brainstorm. It’ll make it easier to choose my next project once I finished the current one. Sometimes in order to maintain my excitement about the in progress project compared to the new ideas I need to jump to a different scene or make something drastic happen that I wasn’t necessarily planning.
I obsessively daydream and lie to myself that one day I'll give these stories the attention they deserve.
The fact they all take place in the same universe eases the pain a little. That way I can still have the characters around somewhere.
Doesn't that make things actually harder? : D at least, it does for me, as all of my stories, even if in different universes, are in some way connected. They all make sense on their own without knowing other stories, but there's an additional part of planning which is 'which story should I go for first so it creates a better experience if someone wanted to read them all' cx
I'm currently transitioning out of one story into another by the end of this year hopefully. My best advice is to ride the thought wave. Everyone is a little different but I find if I just get the obsessive thoughts out on paper for that one part of the new story I keep going over I can put it down for a bit. Shiny and new projects are always gonna be distracting but they're not even close to being ready yet, ya know? So I get the ideas out, feed that shiny and new part of my brain and then remind yourself it's not even close to being a workable project yet.
I don´t see them as distractions.
It´s just new ideas, I have new ideas all the time and at some point I use
the ideas. I wrote a song at the age of 36 and I had the original idea for
the song when I was a teenager. The same with stories, characters etc,
some ideas are really old and I pull them out when I need them.
When you create a lot you will have a lot of ideas, it´s a multiplicator for
ideas. It would suck when you don´t have ideas
See, my secret is to never think far enough to consider the reading experience
But seriously, I kinda assumed that if I do these stories, I'd go by reader response since I've seen it done like that before.
Planning would definitely keep it more harmonious but I have no idea where I'd even start lol
I usually give in to the urge, because it won't go away even if I try to focus on my current project. Sometimes, I need time away from my comic because I get bored with it and start losing the motivation to continue working on it. But I'm not so far in other projects that I'm doing time consuming thing like making pages. I just do backend stuff like character artwork and working on outlines and scripts.
If the idea is a good idea, it usually either comes back to me or stays around nagging me to get it down on paper. If the idea lingers, I sit and focus until it's done. This usually works best for single plot web novels. For serials and other novel styles, I write until I hit the wall before going to the next project. It's been the only way I've been able to make progress on my WIPs
I work on 2 main projects at the same time. One is really dark and the other is fluffy.
The dark project can usually fit any type of new idea.
It will be a long project like really long so I made it possible to fit any new idea with the power of plot armor.
As for my first novel it has a clear end.
It has korean influence so it will end in around 200 chapters or so.
Basically a 100 chapter webtoon in length give or take.
I focus on the first novel by reading romance stories and comedy.
To get in the mood for the second story all I need is music. Darks or an anime with gore (won't have gore but it has plenty of violence). Already mapped out prequel story for second story plus started mapping a sequel.
If I had to say my first story is harder to map since it has a clear ending. I had an idea but each day I am slowly changing the end result.
I am essentially working on 5 stories at once but 4 of them are from the same universe.
Already have the covers designed just need my artist to finish some other things first.
I also need 2 more covers for my first novel.
(The last cover is for a book version with extras I will release on amazon.)
I also finished designing multiple characters for different stories. Still designing more just waiting for inspiration.
Even though I only have 2 main projects they all connect in a sense so I am making merch plus social medias.
All I can say is if you enjoy it, it doesn't feel like work. If you are organized ideas don't get mixed up. I only focus on 1 story when I really need to advance the story by a lot. I will probably focus the next 6 months on my first novel instead of multi tasking as I am now. But once I finish I will re read my other novels to continue.
I kick down the other ideas to the bottom of my interest, of course I took the time to write them down a bit and keep them in a google doc or keep a few sketches in a tiny journal, as if to don't get too invested on it.
Since I don't get paid for my own personal ideas, I don't have much of a motivator to get distracted.
Do you still get satisfaction/enjoyment out of doing the things that are commission rather than your own ideas?
Yep, because
Of course, I do draw things for myself, mostly on the weekends be it fanart or original artwork. The commissions, including the webcomics I draw for are things that I enjoy at it's very root: Drawing and without having to burn my brain thinking too much.
I'm not a very picky person nor someone who wants too much in life, so for as long I can have a comfortable life doing what I like, that's enough for me. I know, a lot of people would and had already told me.
"If I were to have your talent I would be making my own stuff! I'll be doing things with genuine love!"
I already spent most of my childhood and teenage years making personal content enough to be satisfied, so switching to something that allows me to live freely is more than enough.
Personally, the world is not gonna be so thrilled over what ideas come from my mind, I'm not desperate to tell stories, nor I think they are important enough to put time into them, an 1 hour drawing is enough for me. I put lots of love on everything I do.
Here's my solution:
I have PLENTY of ideas and would love to go all out but I have to be aware of my time at home/work/hang-outs/life etc... So, I prioritize ONLY ONE!!!! Which is "Lyza's Sandstorm".
Sometimes, I throw in sketches here and there for other ideas and sometimes posting them on FB/Insta... whatever but I can be disciplined enough to just work on ONE project. It's best to have that one project done well vs. having multiple projects and some can be subpar. Now, if you still wanna do more than one, it's best is have minimum 2 at a time.
One project has the MOST focus on and the other can still have focus but given it more time to work on. Also, you have your personal life to deal with... keep that into consideration. Life, itself, can distract you even if beyond your control.
That's my tip... and try not killing yourself... your health needs priority as well.
for me its just time management
I spend a certain amount of hours on my current project,
and a few hours writing my side project
I don't consider it a distraction if I'm enjoying myself and i plan to get my side comic done eventually though I'm sure its different for everyone.
I think it's partially a blessing and a curse that I'm much farther along in one of my series than the other. There's an incentive for me to keep up momentum, especially since I'm nearing the end of the first section and only chapters away from writing scenes I've had in my head for years.
The other, I haven't started yet, and figuring out how to do so has been kinda tricky. It's easier for me to focus on the series I'm currently doing. Ironic, because the one I haven't started on is more planned out in the long run.
When it comes to ideas within one of those two stories, that becomes a little harder for me to ignore. Sometimes an idea for something in the future resonates so strongly that I end up fixating on it instead of making progress. But I have fun doing it, and it often leads to interesting ideas I can use in the future.
I do as many projects as possible while finding ways to sneak in future story projects into my current one. Basically planting the seeds and creating a connected universe. That way I'm expanding those stories while I'm working on my current one :v
Basically this - or as I'd like to call it, 'just freaking let myself be distracted' 
I think it's a good thing though; I'm glad I'm getting ideas for my future projects this early on because the main one is a very lore-heavy series that kind of needs years of behind-the-scenes development for it to really feel alive; it wouldn't be possible for me to pull that amount of lore out of my backside on the spot when I actually intend to start writing/drawing it
My ideas don't all take place in the same universe, but the vast majority of them do fall into my 2 main ones and I totally feel like that eases the pain quite a bit, though possibly for different reasons than you XD It makes me feel like I'm not scattering my attention into a billion different projects, but rather building upon my existing projects, creating depth rather than breadth 
Ye I basically don't think of reading order experience; I figure that if I'm going to complete them all anyway, they're all going to exist and at that point, readers can read them in whatever order they like (and I can recommend the optimal reading order after the fact :P)
Besides that, my brain would probably draw me into a particular order of creation anyway; if I actually make a deliberate choice to create story X before story Y, that's just tempting fate and making my brain want to do story Y first just to be difficult XD
Yeah there's nothing wrong with feeling inspired to work on another project, that inspiration can be really positive! I second the part about just writing those ideas down somewhere and then moving on.
For me the thing that keeps me laser focused is my long range planning. I know about major dramatic plot points that haven't happened yet, and thinking about them makes me excited to put those pages to paper and see how it unfolds. Something that has been static for me through the comic making process is that I'm primarily doing it just for me. I'm telling a story I want to see told. I'm making the comic that I want to read. Getting to craft it in a way that gets me excited is more than enough to keep me focused.
