If poker is just a hobby I suggest you don't think too much about trying to schedule it in your life.
Work, family, friends and taking care of your body/mind should always come before poker if it not something you must do to get some extra money.
Just play when you have some free time, and if poker seems more fun than some other things you do to relax.
It should be treated as entertainment if you don't plan to depend on it for income.
