Learn on one type of guitar, acoustic is best for a couple of reasons. My favorite reason is becuase they stay in tune longer. Also, I start with the basics on any guitar. After you get some basics down, pick a genre or style of playing and learn as much as you can about it. For example:
If you love Country, learn how to play Country music on the guitar. Once you have a good grasp of playing and have some theory under your belt, you can learn other styles more easily. To much can be confusing and frustrating causing someone to lose focus or quit altogether.
