I've progressively begun to embrace the beauty of suffering.
I have:
>donated the vast majority of my belongings
>deconstructed my bed (I'll sleep on the floor altogether if it doesn't fuck up my health)
>started taking cold showers and baths
>started eating much less and healthier
>etc.

A lot of that isn't really "suffering", but rather the abandonment of irrelevance. I'm trying to face the intrinsic value of life alone and to properly appreciate it for all that it can be.

Can you recommend any books, philosophers, etc. that touch this topic? I realize it plays heavily into Buddhism, so don't be shy to share some of that as well.
