The line I love so much is "If you do the same things that successful people do, you will eventually get the same results. If you don't, you won't".
This hit me like a ton of bricks. Since then I have always tried to emulate a successful person in whatever field I was trying to master.
The only way to get really good at something is to find out how someone else has achieved it, and then do what they did. I truly believe that if someone shows you how to do something, and you work hard enough, you can achieve anything you set your mind to!
