Know your distances.

I have heard many golfers on TV and on the range say that they honestly don't know the distance that they hit their clubs.  They might now a general distance but not a very specific one.  I heard somebody say once that they hit their 8 iron anywhere from 135 to 150.  This caused a major problem because when you are out on the course, you never know which club to use.  Part of the problem is that many people's swings are not even close to being consistent.  One day they try to just hit the ball solidly and the next they try to just hit it as far as they can.  It comes down to being the same golfer everyday instead of constantly changing.  Here is a list of what amateur golfers average distance wise in yards with their clubs so you can compare.
