I'm glad I found this thread! I too have had learning to play guitar on my bucket list for ages, and I finally decided to just do it. I got a new guitar (Seagull S6 Original) for my 41st birthday, and I'm nearly one week into Guitar Fundamentals 1. I love it!!
I was nervous at first--although I have always loved music, I have never played ANY instrument. But as others have mentioned, if you have the love, you're never too old!
