Lucky for Desiigner his first job is popping, but if that ever changes ... the guy showed off his other skill -- motivational speaking!
Desiigner put down the mic and picked up a megaphone to work the crowd Monday outside an Adidas pop-up store in NYC. Yeah, he did a little rapping, but then did his version of a fireside chat ... encouraging fans to keep smiling, and put their problems behind them.
The 20-year-old also made an announcement about his own education goal.
Hint: Diploma, diploma ... diploma, diploma, diploma, diploma, diploma!!
