No wonder you suck due to golf instruction pretty much is clueless in general its not your fault.
I find it funny when I see a PGA well known trainer who people think is good, train someone and my brain is like why do he teach that way as it makes it hard to learn and do?
I talked to some trainers also, and I talk to players also, once you know as I done added 50 yards to someones driver and they hit it long in regard to others in 5 minutes, you have to ask what they are doing in golf.
I see so many posts about what happens inside your head before the impact and I go, dont they know once you start the swing its automatic and no consious interuption is needed?
why do people insist they can control things in a swing action that happens in a second or so that is beyond their own perception during the sequence?
oh yes, your golf instructor said you can do it.
Talent is a conceptual idea people use when they have no clue and make guesses.
its more comforting for people that fail and blame their lack of talent for the reason insetad of something else like drug abuse, or being lazy or simply listening to bad instruction.
In regard to Dan, he is doing a plan, wont mean its a good one.
He works a bit to much, he has bad mechanics IMO, but a good short game, so once he get the ball striking going which is unlikely he be dropping a lot of shots due to the rest of his game is good and solid. he struggles now due to being short and wild.
due to a lack of sequence and pivot.
Talent includes genetics, you were dealt a bad hand having to overcome cancer at 13 and the host of problems that followed. It's a credit to your efforts and determination that you've gotten this far in the sport, but you can't dispute you'd likely be even better had you not had to overcome the physical limitations that you've faced.
