I want to convince my parents that i want to play drums for a living. They want me to be a doctor (they reluctantly bought me a kit) and I wanted to be one too until a few months ago when I really started to look at drumming as a non-hobby. I want to convince them that I gave up the dream of being a doctor and want to play drums even though I have a part time job at McDonalds or something. I'm sure they are gonna say "That's a bunch of non-sense! Are you joking?!" and stuff like that, but I really want them to know how I feel about drumming. Can anyone help me?
