I've been finger picking for approx. eight years. If you really want to learn, check out the masters of it. Chet Atkins who furthered the Merle Travis style is my fav. Lenny Breau who idlized Chet is awesome and to name a few others... Tommy Emanuel, Thom Bresch(Merle's son),Alex DeGrassi, Adrian Legg.

When I first started finger style I couldn't put my mind around it until someone told me to think of it as simply pinching. That works great for the simple piece's like Chet's arrangement of Mr.Sandman. Perhaps you can start there, it is fairly easy.
