Lee is currently on a busy schedule and will compete at the Open Championship in Scotland next weekend, which will mark the third major of his career.
But that is nothing new for the 24-year-old, who is well known for being a workhorse, seldom missing a PGA Tour event to take a short break.
"I never get tired of playing golf.
"It is my job and I just love doing it, and I'm just happy to be out here every week," he said after the Greenbrier.
"But the reason I play so many events was I was really trying to make it into the Presidents Cup this year. It's back in Korea and that's where I was born."
The Presidents Cup, being held in October, is the equivalent of the Ryder Cup, but instead of the United States team taking on Team Europe they play Team International, made up of players from outside Europe.
Team International will be made up of the top-10 ranked eligible players on the Official World Golf Ranking plus two captain's picks.
Lee jumped from 158th on the world rankings to 78th after his win last weekend.
Lee was to tee off his first round at 6am today (NZT) and 1.50am tomorrow.
