Since dad passed away, I've picked up the guitar. It's much harder than most think, but once you get down some basic chords, you can progress pretty easily. I have all the basic chords down and can rough out a few Beatles songs and Browned Eyed Girl. By no means am I ready for the stage, but I'm getting there.
The lesson here is that it's never too late to learn something. Don't say you can't do it. Just put some effort into it. Have patience. Ask questions. Seek the help of others.
You'll get there. Just keep strumming away.
