You don't need to know everything yet. You just need something to work on, repeated on purpose.
Get a whiteboard. Write out what you want in 20 years, no limits. Where you live, who's with you, what a normal Tuesday feels like.
One sentence you come back to always. It doesn't change. Everything else does.
Not what you're good at. Not what you want to be good at. What you're delusional about.
Show up on the obsession every week, no exceptions. This is what actually builds the skill.
Look back. What worked, what didn't, double down. Then check yourself: are you chasing what you're obsessed with, or what you feel you're owed? Are you building around ideas, or around you?
Fill out sections 1 through 3 once, and revisit them if they ever stop feeling true. Do section 4 every week. Do section 5 once a month.
