I decided to get serious about learning last May. This site is great. There is so much to learn and so many styles. I have improved quite a bit since I joined. Now that they have been adding full song lessons, I am really excited and inspired to get good enough to play the ones I really like!
Keep practicing and playing. As with anything, the only way to get good is spend a lot of time doing it!
You will also find all of the teachers are great and more than happy to answer your questions and give tips and pointers!
