Music gave me something that was not only good for me - it gave me something to work on, something to be proud of and something that I really loved and have a love for - but also music was good for other people because you put joy into the world.
When you make music, you're forming these invisible vibrations in the air into different shapes and consistencies and speeds in order to create music, and understanding how the math of that works just gives you more colors to paint with, and allows you to get to what you want quicker.
Music is made up out of these building blocks. Studying how these blocks go together and what they consist of and the math of how it works - it's all the same stuff; it's just different aesthetics that we're talking about.
I worked full time jobs, basically doing manual labor until I could make enough money supporting myself as a musician.
