I'm 35 and just got a guitar for Christmas and I'm really loving it. I don't know any songs yet, but I can do scales without looking at the guitar with no problem along with a lot of string bends and hammer ons and pull offs to make them less boring. I know a lot of chords, but switching between them, even at 40bpm is pretty rough. I'd say i'm at about 30bpm, and my Metronome STARTS at 40, so its a huge pain in the ass right now.

Just remember, it only took Slash 10 years to go from picking up a guitar to rocking out in GnR and being hailed as one of the greats. If he can do it in 10 while being on every drug in the universe, that means you can do it in 5 sober!

Get to goin'!
