I agree with the previous posts, but I was in your situation where i hit a wall on what to do. Sometimes you just need that little guidance that will suddenly "light up the bulb" of what to do.
I do recommend you first use the Life Planning tool in SUN. It will help you determine what kind of businesses align to what you want/wish to do. For example, I had a friend that wanted to spend more time with his family, but started a consulting business that, once succesful, has him traveling 3 weeks a month...he`s actually spending less time now with his family!
You can search for "hot business ideas" on the google, and find a ton of advice. web. I recommend entrepreneur.com list (http://www.entrepreneur.com/hotcenter) and this article is pretty good too ( http://sbinformation.about.com/od/startingabusiness/a/homebu siness.htm). Check out also a forum here in SUN about hot business ideas.
Good luck on your quest. Dont forget to do your Life Plan before picking your business. You may step on a land mine if you dont do it.
Waiting for ideal conditions is rarely an option...SEIZE YOUR FREEDOM!
