Im wondering if this is a common adhd thing.
For example, I have always wanted to program, but I can’t let myself start with some easy gui building block code. I need to understand how the code is interacting with the computer itself and know how they did it in the 80s. Then of course it’s too hard for me and I give up.
Or if im making music, I need to do everything from scratch the hard way, making it as hard as possible (and killing any creative effort i had in the beginning).
It’s the same with anything. I can’t progress if I dont know the absolute reason why something is being done. And if I do it the easy way, I didn’t do it right and took shortcuts so it was worthless.
One thing I can help you with. If you learn bass first, you really learn the structure of songs, and it helps make guitar even easier. Don’t worry about theory honestly. My friend is super into theory and im not really, and we both make complex music. Theory is just words for what you’re already hearing.
