If I had a dollar for every good idea that I've had, I would be a millionaire. Years ago I had an idea for a huge music school for kids. Then I had an idea to start a real estate investing company. Then a studio. Then a music licensing company. Then a music licensing/tech start up. I've had app ideas, career ideas, ideas that were brilliant, some that were horrible, and some just plain goofy.
The thing that made my current company start working and not the others was not the remark-ability of the idea but the will to execute that idea.
Most people have great ideas in them. It's part of being a human. The gene that not everybody possesses is the ability to make things happen. That gene takes some practice.
