Passage of time, which also ties into transitions. Sometimes I just want to write every day in an eventful week of a character but that makes for horrible pacing and takes too long to get to the plot, BUT, I can't just cut that all out because there's useful interaction in those scenes. Montages have saved me more than once in this script.

As for posting, I don't like the sheer amount of social media that doesn't have a scheduling feature, or actively punishes scheduled posts. Pretty sure Twitter tanks my engagement when I need to travel or I'm not home and have to rely on scheduling, because I can post down to the minute manually and see a big difference - this sucks.

Lead-ups to endings are my worst problem in the actual writing process. Like, the ending itself normally goes fast but the last ten k words or so before that are normally reaaaally tough for me. I guess it's because I'm subconsciously afraid to forget to tie up some loose threads. Which is idiotic because I always go over it afterward and revise but I guess the feeling is just hard to shake. The only way to deal with it is powering through and whittle away at it 1k after the other.

The other thing I find really, really tedious is part of my revision/editing process: If I have big revisions to make I do them on PC but for stuff that's more about phrasing/words/spotting typos I like to do it on a printed copy because it makes finding stuff easier for me. The problem is: I have to put all the changes back into the document. And I hate it There is nothing more dull to me than going through the text I've worked through so often by then, making sure not to miss even a single comma I added or crossed out and put it into the document again.
I'm afraid there is no way to get around this though if I want to work on paper. I try to do only a few chapters any given time so it isn't as bad but still. I hate this part to the core.

I hate being desperate to dig myself out of slow parts. It makes me not proud of the slow chapters and feel like I’m rushed.
Or not ending on a sort of note that makes people excited or curious for the next chapter.
But writer’s block is obviously the worst. I usually always have a point I’m to reach, but getting there can sometimes leave me staring at my screen with no motivation.

...English grammar. And finding the right words to not make them repetitive. And finding words to make sure I didn't misinterpreted the word I was going to use. And finding words when I forget what they're called...

Yeah, like that. Ahahahahahahahahahahaha...

Correcting grammar, finding other vocabulary, when I'm stuck in an awkward scene like papapa scene cough

As for posting... I used to get annoyed with posting in tapas since I had to check the whole document again to put italics. Luckily, there's a workaround for it!

Every time I'm writing I get the feeling that I'm not connecting with my characters deep enough and that they are all seeming too similar. Also sometimes when a character is like "Wow they're sexy" while looking at another character I have to check it out over and over to make sure there is a decent amount of respect and its not just objectifying one of my characters

Making sure everything flows together and I didn't miss something. I try to have outlines now but sometimes I deviate from them. So then I get paranoid that I forgot some detail that will mess up the whole story

What I gave trouble with? Well, maybe romance but that is mostly because I am a very unromantic person and no amount of romantic music can change that. I often takes the route by writing people and situations first, then I go oh, these two have really good chemistry, let's try a romance. With other words I rarely write a story with romance in mind but add it in if I notice that there is an opening for it.
And sex scenes… I am just plain horrible. Going in like, "then they had sex." Often I just skip the part. I am the personification of fade to black. Well, it has become a point of mine to write out sex scenes if only because I often write BxB. I started because I wanted to write about the romance between men as all that I have read focus on the sex part. It became more like a porno than an actual romance.
I don't really have a problem with worldbuilding as that is my strongest suit and as an advice, write the world before you start your book. That makes it easier. Especially characters. If you just go on fantasy or inspiration, whatever you call it, then you will encounter the infamous writer block sooner or later. I have never encountered it myself but I know several people who has a hard time with it, most of the time its because they haven't really planned and structured the story in a good way.

A good thing to always ask yourself questions, write out how the character's personality is then ask yourself why? Is it genes? from who? If not, then what happen to make the character this way? Create a picture of the characters childhood and ask yourself how this would affect a person growing up.

You are writing a murder, all the clues are fine but ask yourself why did the murderer do it? Why is everyone reacting the way they do.

Writing about a war, why is there a war? Why are the character fighting it? How has it changed him/her?

Writing a romance, Why did they fall in love? Is it because they are the same? They are different? Do they change each other? How? Should they stay together? If yes, or no, why?

Asking questions also works great to get rid of writer's block. It helps you lose up the knots and start writing again. Back away for a while and look at the whole story, then you might see what your story is lacking.

These are some of my advice, sorry for making it so long

Formatting. **** formatting so hard right in the gullet. Do I tab, do I go in five spaces, do I do an extra space between paragraphs? Do I do that extra space AND the tab? Can I do visual tricks with spaces that work with spaces on word that will translate to the website's uploading process? So many questions.

Like one of my favorite tricks is spacing a word out across the page and bolding or italicing it. Which is fine if the site can translate each space into the correct HTML character of "a non breaking space" shorthand, which 99% of them don't do. Heck, even Discord is like "you put five spaces !!! Truncates to one!" or "you put this hyphen five times. IT SHALL BE ONEEEEE ONE TO RULE THEM ALLLLLL"

When it's just in my word document software:

I am god.

.
When it's out in the wild on the web, I am not. Take that "." just above? I had to put that there because the coding for underneath a heading which is proceeded by ## is that no matter how many paragraphs you make, if they're empty, they don't exist. So you have to put a character for the programming to make the new paragraph. Just. TABLEFLIP. All day long.

Starting the story or day.

I'm not gonna lie, my main story happened to have four different revisions of the prologue since 2015 and I never finished either version. The old link of my comic's summary at Smackjeeves and Comicfury haunts me.

My least favorite part is how my writing turns super depressing when all I want is a happy ending.

If I haven't written for a while, it takes me time to get back in the writing zone. And it's frustrating when I want to write, I know what to write, but the words just don't flow.

Even without having had any romantic experiences in my life, I can tell you romance isn't all that hard to write well. The trick is, you have to read alot of romance. Good romance. Not the fantasy/wish fulfillment stuff. You're going to need to wade through the books whose demographic is "sexually frustrated woman in a midlife crisis who has a glass of wine every night before bed" and find stories with realistic portrayals of romance. Which means it'll be really boring, because real romance isn't usually very flashy.

I love most aspects of the writing process, especially world-building, character development, and fight/action scenes (these are my personal favorite).

My least favorite part of the posting process is no one reading what I've written haha

I'm a habitual under-writer. I get so excited about a scene that I rush everything to get to that one scene. But I can't just write that one scene first and then go write everything else. So I miss out on a lot of opportunities for scenes and the like.

Which also leads me to editing, which I hate with a passion, but force myself to do anyways. I have found that while reading my previous draft, I'll think of new scenes or missed opportunities and I make a giant list of them all so I can go back and do them which gets me really interested in the plot/characters/situations again so I write more. Right now I'm aiming to add 70,000 to an existing project since I can cut stuff later, haha.

I like posting my work, but if I don't, or can't, do so consistently I start to feel bad.

reading and editing my chapter and think its okay before I posting it then minutes later, I reread once again after posting and see typos and grammar errors.

Scenes with a lot of action. I'm never able to outline it right and it comes off as too fast and unnatural. If anyone can give me tips on drawing and writing action scenes, please help :((

Favorite thing to write? Definitely character interactions. I think writing characters has always been my strongest point, lmao.

I am not good at describing the place. I try my level best. But there are always some flaws.

The little tiny edits I do right before posting. Whether it be changing how a word bubble looks or making show the screentone and fill ins aren't sloppy. I just wanna post but I end up dedicating 2+ hrs because I'm anal.

Definitely the posting lol.

I find that there is always problems one way or another. The times when I truly want to just throw my hands up is when I have to write explanations about something within the story and having to describe it in a way that make sense. This is usually during the more tame and quiet moments.

Maybe it's because I grew up with mostly looking at the pew pews and bang bangs but having to write expositions is murder.

Run on sentences. I'm the worst with those. Writing action scenes is a struggle, too. My writing gets really monotonous during action.
Aaaand some ol' inconsistency with my style.
I'm really easily influenced; I'll pick up whatever style from the book I'm reading at that moment. I always have to go back and try to edit it out -cries-
I always hate that moment right after I click publish - like a bolt of anxiety goes through me.
That's always my cue to busy myself with exercise or something else lmao, and then it goes away.

In regards to writing, I'd say my least favorite thing is that I can rarely satisfy myself with a draft. In a way that might be a good thing as it pushes me to try to make a better version, but with how I work I basically end up scrapping an entire draft. I also still feel like my own writing style can be repetitive, but that may be due to being accustomed to it.

As for the posting process, I'd say it's just how slow it is for novels to gain any traction, especially if it's outside the bigger genres. Granted, I could probably use a more appealing cover.
