Failed entrepreneur, broke, unemployed, now taking care of aging parents. Help.
Here's what you need to do.<p>1 - Practice humility and drop the attitude. Stop feeling sorry for yourself.
2 - Come up with a plan to have a net worth of $0 in 18-36 months -- owe nobody anything. If that is impossible to conceive of, make sure that you are exploring all avenues -- including bankruptcy.
3 - Get off the couch. Establish social connections. Go to church. 
Volunteer somewhere. Join a book club. Work in a coop. Do something.
4 - Build your relationship with your parents. Don't "manage" them. Easier said than done, of course.
5 - Work. Anywhere.<p>Sorry to sound like an asshole. Live for the present and don't worry about the future until you have fixed some of the stuff going on now.<p>Print out your post. Your goal shouldn't be starting a company -- on December 8, 2011 you should be able to look back on today and be able to say that life is better, and that you refuse to go backwards again.
