I've jumped back into doodling on guitar after a mid-20's post band break up and... it's totally different this time. I am so much more interested in scales, building chords by manually and so forth, when I was younger I wanted to play songs.

The opposite is true for my math. I enjoyed algebra as a kid and hated trig and calculus. Now I am much more interested in calculus and don't like algebra algebra.

Sometimes there's different ways to learning, I have no idea.
