Ever get the feeling that you could potentially change the world?

I get these bursts of activity in my mind. Nothing very specific, which is why I probably never act on any of them. However, I get this feeling sometimes that I could create something… anything and it would set off this snowball effect that would lead to something great. A website, and invention, writing a novel, starting a company, making a movie. But these thoughts are so quick and fleeting, I never have the time or desire to really develop them. I assume this is not a unique experience and that others have these thoughts as well. Has anyone on here ever played out the scenarios and come up with something interesting, or intriguing? Maybe a little inspiration is all anyone needs.

Please share your thoughts.
