The only way to attain vision is to have reworked and redefined your musical style and ability to the point to where you become aware of yourself as an artist. One cannot tell you what their musical vision is; they can only show you. A musician with a vision has the ability to meld his personality into his music. He/She knows his/her strengths and weaknesses. Every factor is a building block to their music. When you realize your vision as an artist, you will begin to understand what you want, and where you need to go to get it. If you haven’t found it yet, don’t fret. Keep making music and assessing yourself as a musician. It will come in time. Will it help you grow as a musician? Definitely. It will put that extra edge in your music that screams your name whenever people hear it.
