I think you can do it man.
Put over 50% of your time in the short game. Pros practice their short games for 8 hours everyday. You need to be able to get up and down 85% of the time.
Pros also make 95% of 10 foot putts, so make sure to practice your putting a lot.
I hate to say it, but if you can´t carry your 6 iron 200 yards you have 0 chance of making it.
I also suggest bathing in ice water everyday to make you mentally strong. I got this tip from David Toms after he shot the course record at my club (a 58 using only a shovel and baseball bat as clubs)
