I turned 65 back in August and have been irritating guitars since I was 6 years old. Of course, I have now graduated from irritating to annoying them now. ;) I find these guitartricks.com lessons to be just what I needed to help him raise the bar on my playing. Oh, I'll never be a shredder (not my style), but I love being able to pick up a nice guitar and jam with my buddies without looking like a complete putz. Patience and CONSISTENCY IN PRACTICE are the key from what I have seen. I see too many people who try to cram all their practice into a weekend hour or two... better off doing 15-30 minutes DAILY and tracking your progress. It's making a difference in my playing; of that I am sure.

Best of luck!
