It is really easy to have a routine when you are single and healthy in your 20s. It stops working so well later on. If you have friends, partner, kids, parents, pets, work, health issues etc. the routine is going to be challenged. If that only happens once every few months no big deal, but now that I am in my late 30s with a partner, kid, 3 pets and elderly parents. I literally have something derail my day almost every single day. Carefully planning my week would be a recipe for misery.

I think really successful people are ones that just don't give a shit, like full on narcissism. Like my dream is X, I need to do Y today. The dog is sick? My kid needs a ride? My parents need help? Not my problem I am doing Y full stop.
