This is for danielle and others. If you bought your equipment off the shelf in a store, you need to take it all to a clubfitter. Here's why: a good fitter can check your swing then measure you and check the lie angle of the irons and the flex in the club shafts for all clubs. While your swing probably needs the help of a good teacher, a common problem among amateurs is their equipment is wrong for them.
Shafts may be too long or short. The flex may be regular when for girls it should start out much less stiff until they get swing speed up to normal. The lie angle of the irons may be too upright or too flat which affects the trajectory and direction.
One more thing: When using an iron, make really sure your hands are always ahead of the clubhead, commonly beginners don't place the hands ahead and as a consequence they are hitting the ball with no lag which is impossible to get the ball in the air.
Step one: Take your equipment to a good club fitter
Step Two: Take your swing to a good teacher and learn the fundamentals
Step Three: Practice at least 3 times a week
All of this will shorten your learning and frustration curve and you will find the enjoyment this game is meant to give.
