Self-control is crucial for success but is not really something you can get better at. Instead, it's a personality trait. So, if you don't have much of it, you probably never will, and will have to use many life hacks to control your behaviors, e.g., Ozempic.
I confess: I spent decades selling a self-control narrative that was wrong. My new Substack explains why self-control doesn't work the way we thought, and how we accidentally created a moral meritocracy around personality traits we don't choose.
