I go along with Amos too. Learn at least three (easy) chords and keep noodling around with them. You've gotta learn at least three or you'll be stuck playing country-western instead of folk. [Grin]

Find a song you like with those chords and play it all the time. And practice, practice, practice. I started playing in 1985(?) but have never devoted myself to practicing every night. As a consequence I can play the damned thing, barely.
