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.
Although I am a public figure, I'm still a little shy. I don't think my own personality is important. I prefer to keep some small dosage of privacy.
Pray that your loneliness may spur you into finding something to live for, great enough to die for.
