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.
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.
