I think one of the most important lessons to learn in the music industry is to understand who your real friends are. There are a lot of people who may be around you just because of the money or the fame. It's important to surround yourself with positive people who are accomplishing things and who want to see you succeed.
Whatever controls us is our lord. The person who seeks power is controlled by power. The person who seeks acceptance is controlled by acceptance. We do not control ourselves. We are controlled by the lord of our lives.
