I'm procrastinating too, I have Hub titles to work on and don't feel like doing them. I think it's because I just joined hp about six weeks ag and I've been going at it daily, sometimes all day without taking time off. Until I feel like jumping back in, I'm doing a lot of reading and writing snail mail letters.
Your other commenter has good advice. I'm going to try writing only during regular hours, and hope I don't burn out.
Also, my friends and I are challenging each other with topics, maybe you could have someone suggest them for you?
