The following was just my experience.
My suggestion is you read about self-efficacy[0] and do small things which lead to bigger success.
The concept of self-efficacy was a huge eye opener for me.
Maybe for you as well.
When you like to write a book try writing one paragraph now. Do things you can do 100% and do it. Daily something. Tomorrow you you maybe read one article about a topic you find interesting. Then you bake something, cook something and join a class with people who also like to draw?
Try to give yourself time and don't try to do things you can't do yet.
Focus on progress instead goals and see what happens.
I've built an app with a nocode tool for me in a afternoon exactly for this. Maybe this is helpful for you? focusonprogressnotgoals.250g.dev
You are on hackernews, so i guess you're interested in coding or tech. Write your own app to solve this or just use a nocode tool and click something together in an evening?
