One thing I used to do when I was starting off was to play the song with my eyes closed. Obviously this has to be done once you've got the hang of the song with your eyes open! But anyway I reckon this method increases your feel for the guitar. You know exactly how far to move you left hand and where to pick with your right hand without actually looking at the guitar at all.

Dunno what the other users will think of my suggestion but there we go! :D
