Drive it farther or Hit long irons better

For hack golfers like myself, it is a lot harder to put a 3 iron shot onto the green than it is to put a 7 iron up there.  Unfortunately, my drives usually leave me in a position where I am much longer than a 7 iron out on my approach shot.  I figure there are two solutions to this problem.  The first one is to drive the ball farther.  For me, it seems the harder I swing with my driver the less desirable the result is.  The second solution to the problem is to hit my long irons better.  I told a 2-handicap friend of mine that I could not hit my long irons and I was getting to the point that I was afraid to pull them out of the bag.  He simply said “choke up”.  This advice helped me get over my fear of the 3 iron but that doesn’t mean that I can put it where I want.  Here are a few videos which may help you do one or the other better:
