I took lessons for about a month. The guy I was taking them from would show me a chord, I'd try it, he'd take my guitar and show me again...

...then he'd say, "And when you get really good, you'll be able to do this!" and then go on to jam on my guitar while I watched for 45 minutes.

He did this twice before I quit taking lessons from him. Now I've found this site and there's no looking back.
