A guitar is a very personal extension of the person playing it. You have to be emotionally and spiritually connected to your instrument. I'm very brutal on my instruments, but not all the time.
I have this dream life where I get to be a celebrity but I get to navigate the world fairly easily because I'm always in character.
Are you bored with life? Then throw yourself into some work you believe in with all your heart, live for it, die for it, and you will find happiness that you had thought could never be yours.
