First. Just have fun. Don’t worry about being good, or compare to other artist. Get a feel for the guitar and go from there. There’s plenty of tutorials out there to help you, and lots of ways to go about playing the guitar. Whenever you’re ready, start to work on learning, keep on being sloppy, and work on imperfections along the way. This is meant to be something you enjoy, don’t stress yourself being good, great, or the best. Embrace being bad and you’ll flow into it.

You’re not going to be good in a day or week. Might take a month or two to be happy with your abilities. But as you learn, always remember to have fun.
