Well, while I have goals for my work I'm hoping to reach, I don't know what I'd consider success in the comic world.
I have a decent amount of subs(530 if you're interested) and about 50% seem active. They're wonderful people and I'm happy for that 
It changes from day to day. Some days I feel great about it. Some days I question my sanity. Overall though, no, probably not successful. I can compartmentalize the levels of success, but as I look at the sum I don't feel successful.
at first I thought I was, but now I'm pretty unhappy with the drop in activity. I think my comic's been getting better, but I feel like I should have a bigger amount of people who are actually interested compared to the amount of subscribers I have
I think that equating success with subscribers and activity is a road to discouragement, because you don’t really have that much control over how popular your comic gets in x period of time. Setting goals that you know you can work towards is more encouraging, at least for me!
I didn’t think that I’d be able to make a webcomic because I was sick due to a brain tumor for a very long time. The fact that I can draw pages each week and improve my art is success enough for me right now, haha!
I've been at it for a few years now. I'm still unknown and have very few subscribers. A lot of people would probably think that I'm very unsuccessful, but to be completely honest... even though it looks very unpopular online, it's doing quite well in print versions. It's a hit at conventions and the people who bought the first few issues, bought the latest one that came out this year.
So, I guess being successful depends how you look at it.
It's a long series and it starts out pretty slow. I'm not sad when I see these numbers. Just to see that people are reading and enjoying it is wonderful. For some, it's even their favourite comic, so I'm over the moon.
Just getting started with RUDE PANDA and I feel I could do better as far as fans and income but I feel that I am successful when I keep to my deadlines and am still able to create a fun looking comic with some laughs.
I feel like somewhat successful
I can't live from all my comic income as of yet and I have by far not as many subscribers as many popular comics.
However, with the income I'm able to pay most of my monthly bills and a large amount of my fanbase is very energetic and invested in my work.
I feel this is a good personal success and makes me feel like there is still ways to grow (income and sub wise). I'm positive about the future 
After 3 years of working at it I think I'm moderately successful.
I have a good number of fans who are genuinely interested in my stories.
I definitely don't make enough to support myself, BUT I like having this extra money to spend on small things to make me happy.
And mind y'all this is 3 years of hard work. I can only push forward and imagine where I'll be in another 3 years.
I'm pretty happy with where I'm at right now, as a complete newbie to the comic scene The fact that I've only been publishing for a few weeks and am already in the double digits of subscribers and have a couple hundred views already is pretty exciting/encouraging! Like many others have stated, I wouldn't be stoked if I plateaued at this point, certainly. But in the here and now, feeling pretty good, and enthusiastic for the future 
In terms of popularity and income, no. Not at all. There is no money and my comic is "invisible", certainly won't be trending soon. But I'm extremely happy with the interaction and my subs are enjoining the comic! Sometimes I get more likes and comments per update than some comics with massive a massive following.
I'm a very goal oriented person and very competitive, but the comic has been my place to chill and share. I'm surprised that I genuinely don't care about the numbers and money. I'm happy.
I'm happy with how it goes, sure i don't make any money with it but i'm really really glad and thankfull that people seem to really like the story and the drawings so far even tho, i made a mess of the few first chapters and it's really confusing... It was intentionnal at some point but after looking at it, well... It felt like it's kind of clumsy because it confuse the reader... I just wish i was way better and faster at delivering the story, i'm miles ahead in my head but drawing just takes ages...
I made the mistake of going for publishing first with Tom N Artie instead of doing webcomic first now things have kinda become a weird topsy-turvy kinda deal where it's kind-of working out but at other times not. I don't know how to describe it.
I haven't been successful in terms of popularity and income. I consider my web comic to be successful as long as I continue to improve it, even if I don't get income and popularity. If I quit making new pages before the planned end of my web comic, then I would consider my web comic a failure.
Something different: I think I have been successful!
I actually finished a comic! Deerstalker was only 40 pages but this was significant to me. I managed to finish it senior year of high school while balancing all the other things going on at that time.
No, it's not financially successful, I never tried to sell it or ask for donations but that's not really important to me. Instead, it'll always be a reminder that I can actually finish a project from start to end, and that it is possible to manage my time and work a little bit each day.
We just had our first print run funded on Kickstarter, so yes, I'd call that a great success! Not much in the way of net profit, per se, but that wasn't our goal going in.
Mmm... Kinda? I'm successful in the sense that my story got a lot more attention than I expected it to receive. I'm not gonna lie, when I posted my comic a year ago I really expected it to go famous overnight (i know, i know.. 
). I was looking at all the other comics on the front page, examining what made them so popular.. One shot gags, a clean art style, bright colors, characters in their teens-20s... I made sure I included all of those and didn't really even think twice about a deeper concept before submitting it.
But after thirsting after fame for months and months, and being featured in the daily snack a couple of times, I realized that the sudden burst of happiness when I saw that I had gained subscribers only lasted for a moment. Then it was back to wanting more... I couldn't really get my mind off of numbers and found myself stressing over the feedback each time I posted.
"Ugh! How come this update didn't get as many views as last week's? Is it because Tuesdays don't have much traffic?"
"Man, did I really lose 10 subscribers this week?? Was it the content?? The art? Was it boring? i suck."
I realized that I wasn't ever going to be satisfied if I kept obsessing over numbers like that. So I decided to actually do something with Leftovers and give it a story. I turned my main character into a fame-obsessed artist who worried too much about numbers. That way it became much more personal and motivated me to work on it more. It's like Art Spiegelman said: why bother spending so much time on a story if it's not worth telling? Or something like that.
So yes, in that sense, I feel like I am successful with my comic since in the process of making it, I've taught myself something. The theme of Leftovers is just an important lesson I have to keep reminding myself whenever I post an update.
