+1 to this. It's a case of necessary and sufficient conditions. You have to "do stuff" to be famous, but that's not enough, not by a long shot. Most famous people are famous because they work hard at being famous.

Here's the formula for getting famous:

1) Do stuff

2) Relentlessly promote what you did in step 1

3) Repeat step 2
