Do not feel despondent, this game is difficult to learn and the higher you tier up, the more challenges you will come across.
Obviously better clubs will help, G25;s are a great set but it depends whether you want to invest in better sticks to improve,
Other than that, learn all the types of shots - some work better than others, especially around the green (a 3 good wedges will vastly improve your short game). Punch is a great shot too....not only from the rough but from the fairways - like additional clubs in your bag and reduces the need to "manufacture" shots (reducing power too much). learn the affect of using different spin and take notes on distances etc.
But practice and writing notes is the key - be like a sponge and play with better players....and ask questions.
Read and search the forums for info - great tips in here from top players.
Like real golf, no two shots are ever the same, but have fun in learning what works best with your clubs and shots.
