What does "stopped picking up" mean?
Otherwise, I completely agree that not drinking also means a complete overhaul of your life...a growing up, if you will.
I think that's what Peterson meant when he said that alcohol had to be replaced by something better. That better thing has to be something that is meaningful, responsible, and enduring (like the things you mentioned). It can't just be another person, though it can certainly include other people.
Picking up the glass/bottle.
Absolutely agree with you.
