Over the past half century, America has moved from a culture of self-effacement to a culture of self-expression: think Twitter, Instagram, Tumblr, etc. A TIME magazine cover once called out the "Me, Me, Me Generation" and the ways today's culture and technologies feed a present narcissism. But even with this apparent rise of self-love, there's also an institutional bent in Millennials that wasn't there in Gen X. So is it "me" or "we"? No matter the answer, it's time to rediscover the power of humility.
