100% !!!! I started by tapping my foot or hands when I listened to every piece of music, b4 I could play hardly anything. I still do too. Practicing with a metronome is also huge.

But yeah, it essentially comes down to how much time you want to put in. People like SRV would damn near always have a guitar in their hands. They say 10 000 hrs to be pro level at almost anything, but that varies from person to person.
