around the same age, i was lucky enough to start playing, and develop a good relationship with the head pros around my town, and they would allow me to play their courses for free, as long as i walked.
try and talk to those guys, and maybe get some discounted rates, or work out a deal to play for free, golf's definately not cheap when you pay green fees.
most of all dude, just play alot.
you will gain alot of experience around other talented guys, and by just practice, practice, practice.
trust me, the 1st time i ever broke 90 i shot 81, you will just get to where it is natural motion, then work out the kinks.
have fun, dude, its a great sport that alot of people have come to love
