Who do you look up to? Figure out why and then determie if she or he will make your life better. I'm talking about people in your personal circle as well as celebrities. The people in your personal circle have direct impact on your life because they see you and talk to you more frequently than a famous person. Take their constructive criticism as admiration and guidance, if they're your friend too, chances are they admire you in many ways too, it's all in the delivery. Sometimes tough and sometimes sweet, take it all in.
