I don't see it that way. If there's always something you have to be doing, then that's the life you chose. Yeah, there's some things that are usually necessary. Your job will take a third, sleep another third and the rest is up to you to decide. If the remaining third is spent doing things you don't like doing the majority of the time, then change it.
My life is fucking boring, but I can say I spend my third doing exactly what I want. There's odd things in there that come along and take time away but they aren't a constant. Want to live this life? Say no, do less, chill more. Life is what you make it.
