You know, perhaps the problem is that you're taking on too much at once, where the whole experience has become too overwhelming? Of course its important to dabble with different techniques, but its really important to take a stepback from what you're doing, and ask yourself what type of style best (naturally) suits you. and with guitar lessons, its not something you should be afraid of or take very lightly, be sure to take some advise here and there from your closest friends, and watch the positions of their fingers. Remember there is a right way to learn, and a wrong way, sometimes if you can't figure out the difference by yourself, then its very important to seek assistence. There are some great websites all over the net, just remember to slow down and take it easy...
