alright, i was in your same position about 6 years ago. at first i thought i was WAY over my head.

one thing i learned i didn't like teachers. i thought my self because i found that books and Cd's work best. but what ever you think you learn best at go for it.

Frist thing to keep in mind while trying to play.
you don't get good over night. it can take Day's, weeks, month's and years. just to learn just a hand full of songs.
