Maybe PD guilt is a symptom of perfectionism. You think of what you 'should' be doing to improve your character or make a better life for yourself and feel guilty if sleeping in isn't on that list.
Question - Why the heck isn't sleeping in on your PD list?!?
Doesn't improving your life mean liking your life? If you're going to eliminate the 'indulgences' you love from your life, doesn't that defeat the purpose? Maybe finding yourself frequently not doing the things that you believe are on your PD path (and feeling guilty about it) is a sign that you need to rethink some of your goals. Maybe they're not your goals. Maybe they're goals other people think are worthwhile and you've mistaken them for your own.
My dream is to be able to sleep in at least once a week, knowing that my life is running smoothly enough that things won't fall apart if I snooze a couple extra hours. *sigh*
