Best golf advice I received: STOP ASKING FOR TIPS & POINTERS!
Find yourself ONE golf book instructional (the Pennick suggestion is a good one) and just focus on playing. You see, people get too many tips at once, try all the 1000 things they heard and then up mastering none of them. You simply can't give each tip enough time to actually work for you if you keep on changing them! Just follow one instructional book and give yourself enough time to actually develop your game.
Also, too many people focus on the range and the driver. Forget going out and buying the latest $300 driver. Get yourself a good set of wedges and work on the short game. I almost always play on the chipping green, sand trap and spend very little time at the range.
