I tried to replace alcohol with some other single activity to directly substitute. It hasn't worked. Instead, I'm letting myself indulge in multiple interests. Drinking was the only thing at which I have ever cared to become proficient. Realizing my own personality limitations have led to more peace about what I choose to do instead of drink. I didn't want to have a bunch of interests all at once, but I found it the best framework for keeping myself busy and interested in healthy designs.
