WHICH PRACTICE TODAY?

I wake up early to a free morning..do I jump on the mat and start with sun salutes, do I do a Kundalini Yoga set or skip the set and chant the hour long sadhana chants ( I really like this choice) or do I turn on the fabulous YOGA NIDRA cd that a student loaned me and that I have on my i-pod but have never been able to find anywhere else and allow myself 45 minutes of Yoga Sleep to her melodious Indian accent? I read about yogis who need little sleep and after 25 years of practice am I to feel guilty that I LIKE my 6-8 hours of sleep and seem happier and healthier and more clear that way? Does that make me a bad yogi? These are the questions that go through my mind on this Saturday morning.
