I've never had a lesson in my life... I think I've came pretty far. A friend and I started playing at the same time and we learned together... But different people have different learning styles. Some people learn by doing and some people learn by listening. It just depends on how you respond to the two different ways of learning. If you consider yourself a visual learner then I would say get lessons... atleast until you feel comfortable with the guitar. If you prefer hands on learning and independent learning then I would say try to pick up some beginner books and start there.
