I don't know. I manage most of these things. The one I am most likely to potentially fail at is "have interesting hobbies," I guess. I'm a member of two book clubs, read poetry for pleasure, and publish on my poetry blog about 3x/month. It doesn't feel like a lot, there is a lot more I could do. Those also sound like relatively boring hobbies to me, "Oh I read and write." Everything else, including "get enough sleep," I manage well - or well enough. That is, I haven't spoken to my mom in 2 weeks, but it doesn't bother me. I even tried calling her the other day! But I'm very close with my siblings so I figure they take up any "time void" that would be left by a lack of closeness with my mother. I consider "decent personal hygiene," "get enough sleep," and "keep fit and eat healthy" requirements, not options.
What other hobbies do I do. Hmm. Drinking?40+ hours weekly, practice decent personal hygiene, keep fit and eat healthy, nurture social, romantic, and familial relationships, stay well informed, have interesting hobbies, deal with unexpected hurdles, get enough sleep, and take time to pause for even just a few moments of reflection.
