Find someone who is already living and producing results at a level you admire and aspire towards. They could be an author, speaker, actor, blogger, professor it doesn’t really matter. The key is to study these people. Read books or articles they have written a number of times. Study their mannerisms when they speak or perform. Notice the way they carry themselves publicly.
Ultimately, the goal here is to understand how they think so that you can emulate the same kind of thinking in your life. I’m not saying you are trying to be like the person because we are all unique and we need to celebrate our uniqueness. Rather, I am suggesting that you figure out the intangibles that made this person so admirable to begin with and incorporate those intangibles into your own behaviour.
