Hello Dan!

It's never too late to start learning a new skill!

Learning to play the guitar (or any instrument) is one of the most frustrating but at the same time invigorating and rewarding things out there. You've signed to learn for life. But at the same time, you will pretty soon start finding fun things to play. Just open your mind and tastes a bit and leave the Satriani songs for a while; you will find many easy and fun things to play that you may not have even considered listening to.

Good luck!

PS: You got a Pacifica? 112? That's a very nice starter!
