Corey, like every other top tier player, put the time and effort in, and had enough ability to become a champion.
He like so many others before him, discover one day, that the reward for 100% dedication is not enough to warrant the effort.
So he now puts in, only the time he wants, to achieve his goals.
It must be extremely difficult, for a guy as young as he was, to be at the top, and realize there is no where else to go.
Would anyone be able to go get a 8 to 5 job, at anything, after the kind of life he had lived by age 25?
Fame and making large amounts of money in short time frames must be fantastic while it is happening.
It must also be a terrific stumbling block when it's over.
Someone told me he was trying to get his card to be a pro golfer, I wish him all the best.
