i went from being very into self-improvement stuff, then to thinking it was all corny slop for a few years, and now i'm back into it but through the lens of self-study. i see it now as just trying to get better at the meta-game of living, which is an infinite game

I did the same with food.  Cutting out almost all processed foods and trying to make a majority of meals myself (daily or with meal prep.) 

Getting a big freezer is one of the healthiest things I ever did, it also paid for itself in a few months.
