My process is a continual cycle of accidental discovery followed by forgetting how to draw, then rediscovery followed by more forgetting and sharp increase of anxiety. I will hit moments of surprise (ie "Wait, I did this?"), but they usually precede a mini art slump where I question my abilities.
And then I make more art. It's best not to think about it too much.
I try to always expose myself to tutorials, and rarely one will make something click in a big way.
What I've found to be most helpful is to always be focusing on at least 6 different projects at a time - focusing on whatever I need to to keep the wheels running. The trick is to make sure to not wrap up all of your interests into one project, but spread them out a bit so you don't feel like you're always working on the same thing every day (or you don't come up with a good idea that you can't use because you don't have a pulp space opera comic to work on).
Haha, it happens with music, too
My biggest works were usually when I learned about a new era, or the workings of a style, and used what I knew about it from other artists to patch together something of my own
Without a framework like that, there were usually way too many different places to go, and so I would go to both all and none of them

Oh thank God, I'm not the only one.
How do you get back on track? Do you find books or look at tutorials on YouTube or whatnot?
