"When I was younger, I was a very shy guy. I often wondered how it would feel to be confident like a rap star. I mean, does Snoop Dogg ever feel insecure? Could you picture a shy rap star?"
Ok, a rap star is propably a high stake? So aim for something different, something of more interest to you. Either way, why not think big? Start small, take 1 step at a time, but do it.
It is not worth staying around just to get dust and spiderwebs around yourself. Shake it! As said in the article, even if you start by immitating something you like, that is one way to breaktrough. Just get it started, will ya?
