How do you stick to writing one idea

In the past three weeks I've been fluctuating between writing three different book ideas and as a result I've accomplished next to nothing. Anyone have any tips?

I don't know… How do you stick to writing one idea? glances at my "story" which is basically just a pile of puked up ideas that I haven't worked on because I'm too busy shipping my characters

lol 10/10 quality advice

I also have three different books (not really) and I'm in the same predicament you are in. I guess what you could try to do is just focus on the one you feel most invested/interested in, and write the heck out of that one.

The problem is that the one I'm most interested seems to change all of the time. It's a struggle :/

What do you mean stick to a plot? That’s impossible for me!

hahahahahahahahahahahahahahaahahahahhahahahahahahahahahahahahahahahahhahahahahahahahahHhahaHhHhhHhahahahahahhahHhaAHAJAHAHAHAHHAHAHAHHAAHHAHAHAHAHHAH

oof well at least we're all in the same boat

Lol, that's for sure… If this isn't the best community for the real side of being a writer (AKA writer's block, work-caused depression and stress, this…), I don't know what is!
I'm a firm believer of embracing chaos. For me, this is the idea that you should always have something to write, but 'something' is pretty broad, so that can be one novel you're totally into or 60 pieces you switch off on. It's fine to have more than one thing you're working on. I think the real struggle is learning to finish; I personally always hit a wall and feel like I have to stop. For that, my darling, you just gotta practice. And remember: Mind before material. Your mental state is more important than your material stuff (books and stories)!
