Regarding lessons... up until last summer, I had never swung a club before, so I wanted to learn how to swing properly. I've now been taking lessons pretty consistently for about a year, and it's amazing how much I've learned about the golf swing, chipping, course management, etc. Maybe a year is too long for lessons, but I would suggest getting at least more than one or two because you can pick up some bad habits practicing that are a lot harder to correct as time goes on... especially if you really wanna learn the game the correct way. Some of my friends' swings are horrible, and I'm really glad I took the time to learn from a pro instead of teaching myself.
just my 2 cents...
