Sometimes, reading my own media, the negativity can upset me, but I just deal with things on a positive basis. I mean, I have up to 20,000 people singing my words back to me on a nightly basis - they share my hopes and fears, and they relate to my own life experiences. Life can be pretty isolating, but that connection is always amazing.
If you have good songs and a real desire to make music, the next thing to do, instead of approach record companies, is to get yourself a really good manager because then it allows you to focus on your profession of being a musician. Then they can focus on the darker art of the record label and the music industry.
