My initial reaction is; bro you ain't gonna be happy when you are scratch! But happy is relative and it will be a heck of an accomplishment. What then? Competition? Continue to improve? Shoot your age?
Quit the game? It might be really hard to adjust to getting worse as you get older once you climb the mountain.
Of course it is possible that you won't make it to scratch... I guess it comes down to why we play the silly game in the first place.
