What the other person said: practice in public. You’ll learn faster and actually get stuff done. It’ll feel like walking down Main Street with no clothes on, but you’ll actually make progress.
I started a writing club on here specifically because I’m such trash at holding myself accountable to creative stuff. And it’s not like I’m Isaac Asimov now, but I’m definitely making more stuff than if I hadn’t tried.
Anyway, I know it’s easier said than done, and actual execution can feel so uncomfortable, but I recommend it.
