The only "secret trick" to play guitar that I know is practice, practice, practice. Nothing beats everyday practice, even it is for 10 minutes. Not even telling what you can achieve with 4 hours daily practice. The continuous interaction with your instrument, will make you learn that when you hear a sequence of musical notes, your fingers would naturally went to the correct position on the neck to reproduce it, even without thinking.

Agreed, and I slightly hesitated to use that phrase, but I do think the "sing and play" exercise is a uniquely good thing to practice, practice, practice. It just seems to really work to connect the part of your brain that comes up with melodies to the part of your brain that runs the fingers. YMMV, of course.
