I firmly believe anyone can get to a sub 5 handicap. And most people can smoke drives 230-300 on a regular basis (depending on flexibility, age, etc)
The problem is everyone over-complicates things.
Think about it. You see professional athletes in other sports completely fail at golf. I'm talking world class athletes with hand-eye coordination and flexibility us plebs can't even dream of.
IMO where 95%+ golfers go wrong is flipping the club through impact as it is such a natural motion.
Slide/turn your hips on the way down and flying wedge it through impact. That's #1 guys. from chipping to driving to irons to fareway woods...it's all the same motion
It'll turn your game from "I don't know if I'll shoot 110 or 85" to 75 to 84
