Michelle Obama
The former first lady reflected on her college years while also congratulating the Princeton class of 2018 with this open and honest caption. "This is me at Princeton in the early 1980s. I know that being a first-generation college student can be scary, because it was scary for me. I was black and from a working-class neighborhood in Chicago, while Princeton’s student body was generally white and well-to-do. I’d never stood out in a crowd or a classroom because of the color of my skin before. But I found close friends and a mentor who gave me the confidence to be myself. Going to college is hard work, but every day I meet people whose lives have been profoundly changed by education, just as mine was. My advice to students is to be brave and stay with it. Congratulations to the Class of 2018!"
