He's not...

A rock star is not someone who takes the temperature, who gauges the marketplace before he creates his "art". A rock star is someone who needs to create and is willing to tolerate the haters along with the fans. He’s someone who incites controversy just by existing. That’s what we lost in the dash for cash. Unique voices. I’m not saying we haven’t ended up with some pleasant music, but it just hasn’t hit you in the gut, it’s the aural equivalent of Splenda, it might do the trick, but it’s not the real thing. The real thing grabs your attention, drives down deep into your heart and lodges itself there. A rock star doesn’t follow conventions, doesn’t go disco or add drum machines just because everybody else does. A rock star exists in his own unique space, and if you met him you probably wouldn’t like him. Because he tends to be self-focused to the point of being narcissistic. Because he cares. He needs to get his message out.
"Some people want to do things because they are interesting.
Some people want to do things because they work.
Some people want to do things because everyone else is doing them.
And some people are satisfied/scared/shy/lazy and don't do anything.
Think about blogging or buying a new pair of shoes or voting for a candidate or picking one career over another. Different people have very different agendas. The key in understanding someone's actions is understanding their agenda.
That salesperson who does everything by the book is not interested in the thrill of discovery. That retired steel worker that is hesitating to vote for your candidate is wondering what everyone else is going to do. And that unpredictable blogger keeps changing the rules because the rules bore him."
