Hey,
Very interesting question. Well, as for me, I usually gets up at about 6:00 as I need to get to my work by 8:00. Sometimes it is really hard to pull yourself together and go to work :). I recommend to drink a cup of coffee, eat some breakfast( I like to eat bananas :) ), do some physical exercises and after that I guarantee you will fell better.

I think the best way to sell your books is to use amazon or eBay. Very comfortable and easy to use!
