In fact, the sheer abundance of things to practice just makes the anxiety worse.
I used to feel the same way!
When I was younger, I’d decide “this is the week I’m working on walking basslines!” Then I’d get bored, or frustrated, then something else would come along: maybe slap-bass.
A week later, I’d decide I was sick of the whole enterprise, and maybe I just needed a new P-Bass.
I’d hear stories about my heroes practicing 4, 5, even 6 hours-a-day, and think “maybe I have to do that.”
But all I’d end up practicing were the same warmups…the same scales and arpeggios… and the same exercises out of books. It was hard to tell if anything was working, and I was constantly frustrated.
