You may remember Karen Cheng as the former Microsoft exec who resigned from her job a few years ago via a song posted to YouTube called “Bye, Bye, Excel and I.” So what has she been doing since quitting her job? Teaching herself to dance, man. Cheng has posted this amaaaaaaazing YouTube video of her journey which concludes in an insanely awesome performance in a San Francisco train station. Seriously, it’ll blow your mind and inspire you to take a dance class or two yourself. Check it out above!
