Thanks for the suggestions, I've got an R/C model airplane which I was building a few months ago and I can't seem to get any interest in my hobbies anymore. Maybe I've got some depression. I'll work on my problem and try to see just what's wrong with my attitude. I think it proceeded my operation and it just made it worse. My brother seems to always have something he's interested in and maybe I can go see him and catch his enthusiasm on some project.
Skully, thanks for the offer of books, I have several to read and maybe that's a good idea. No need to send me any, but thanks anyway. I feel better already.
