I talk to people all the time who want to be entrepreneurs, but can’t find a good idea to work on.
If this is you, stop. Stop thinking about ideas, and start doing shit!
This is the premise of New York Times bestselling author and co-founder of PBwiki Ramit Sethi. Sethi wrote about this in a blog post from 2005 (I know I have been digging back in the web archive) titled The Myth of the Great Idea.
Success almost never comes from a mind-blowing idea, so sitting around trying to find one is a waste of time. Success comes from a basic idea executed amazingly well. Ideas are rarely found by thinking. They’re found by doing.
