NBA draft pick Thon Maker didn't need a college education to make a highly intelligent move Thursday night -- blowing off all the raging celebratory parties in NYC ... to focus on business!
Thon was taken with #10 overall pick by the Milwaukee Bucks -- but after his name was called, the 19-year-old told TMZ Sports there was no way he was hitting the town ... he was hittin' the hay instead.
"I'm going to sleep," Maker said ... "I got an early flight, I got practice tomorrow, and a press conference ... I'm going to sleep."
Pretty mature -- this guy really only 19?
