It harms you. One day you'll want to accomplish something and you won't have the tools. There are thousands of musicians who quit for every one having fun. You will have a better, more fulfilling time if you study music.
so I learned to make my own. then i thought using premade skins was cheating, so I killed a goat and skinned it. I then thought that that was cheating too, so l grew my own goat from a baby goat, I also think that is cheating, but I'm not sure where to go from here. i haven't made any music lately, what with the goat farming and all.
I am not afraid to make mistakes and am even happier if I discovered something on my own that probably any music student would have learned in the first class.
So I'll tip my hat to you for having such a deep passion for music, but I will still move along my own path
