Major cheat code in life: Understanding you can reinvent yourself at any time. New habits, new standards, new friend group, new career, etc. There's no rule that says you have to stay the person you've always been. You're allowed to decide––"I'm done being this version of me."
Be boring in the right ways. Go to bed early. Wake up early. Eat simple foods. Save money. Exercise. Read old books. Avoid drama. Boring is seriously underrated.
