I guess one of the reasons that I find it so difficult to find or come up with a great idea is because I am looking for an idea within my ability and resources - within my ability to execute as a single founder - within my coding, design and marketing ability and with a minimum amount of money.

For example something like www.metrolyrics.com is within my ability to execute. I wish I came up with that idea. Oh well. Anyway the story of this site and his founder is very educational. I can't find the link right now.
