You need to physically increase your drive and attitude to want to improve. What you've shown so far with just an average of 2.5 rounds per week just won't cut it. This game, you need to play and play with the aforementioned attitude plus scan these forums for all the tips and advice you can find.
If you're one of those who just wants to sit on his arze and wait for it to come you forget it. For the first month I played I knocked out 30+ 18-hole rounds a day. Now I'm not suggesting that's what you have to do or even can do but it gives you an inkling that application and dedication is required
You need a thorough overhaul of your equipment.
Oh and if you ever see alanti green then call the Guinness Book of World Records because that would be rarer than seeing a yeti.
