Try making your starting canvas not white. It's a tactic many writers do.
You also just have to do it. Just block in shapes. Draw things you're familiar with as warm ups. Even if they don't come out good, that's what warm ups are for.
You could also get stoned, but don't get dependent on it if you do.>>4870887
For anime, all you really need to do is use MAL. You could see whats trending on Netflix or Twitter. Could even draw for big internet creators. Sexy lewd stuff is fine too. I've seen many people get growth without drawing any actual sex, but just regular nudity or even "cute censorship" with their lewds. Combine it with pandering and you'll get growth for certain, but definitely keep it sparingly if you aren't interested in drawing NSFW content.
I've seen people go ham with fan art, but I've also seen people do mostly their original stuff and just sprinkle in fan art. Growth is slower, but I've seen it work out.
Good luck bro.
