Since I was a kid, but I can't read a note, and I don't have the patience to even learn tab, I tried it and got frustrated, but I can hear any tone and blend in like water so I guess I play by ear and I can pretty much pick up any musical instrument and just play.
I'm terrible at math and paying attention to written material but music is one thing that just comes natural to me.
I'd probably be pretty dangerous if I could read music and apply it to the fretboard though, but that won't happen any time soon.
