The most important club in your bag is your putter. Practice this more than your other clubs.
Learn to hit pitch and chip shots, mid and long range shots in the general direction where you are aiming. Once you can do this, learn to shape your shots.
When in the driving range, always aim at something. This way, you can gauge the accuracy of your shot. Follow the 10% accuracy Rule. If you are at 100 yards, you should hit inside 10 feet of the flag.
Practice the follwoing shots until you gain consistency and confidence that you can hit these shots 70% of the time. Figure out which club works for each of the distances you are practicing.

If you would like to study your game in more detail, try tracking your game shot by shot. Keep track of Fairways hit, Greens in Regulation (GIR), Putts and penalties. Over time, you’ll start to see trends and patterns that will surprise you. If you use software to help you do this, you can see graphs, percentages and more.
For example, if you are putting 36 times per round, well that is good, but 32 would be better. If you don’t hit greens often, practice short and mid irons. If you miss fairways off the tee box, the practice accuracy with your long range clubs. When in doubt, take a golf lesson!
