For me, my guilty pleasure is that if I don't want to do anything one day, I won't. I'll just sit around, not shower, hardly even eat, and just watch TV.
I'm really quite happy to say that in my early 40s, I wake up feeling sexy, and I can't say I felt that way in my late 20s.
I am waiting for a sign that will indicate to me what meaning I must give to my life, but right now my existence is satisfactory.
