Inside the mind of a master procrastinator | Tim Urban

How to stay calm when you know you'll be stressed | Daniel Levitin

You're not at your best when you're stressed. In fact, your brain has evolved over millennia to release cortisol in stressful situations, inhibiting rational, logical thinking but potentially helping you survive, say, being attacked by a lion. Neuroscientist Daniel Levitin thinks there's a way to avoid making critical mistakes in stressful situations, when your thinking becomes clouded — the pre-mortem. We all are going to fail now and then, he says. The idea is to think ahead to what those failures might be.

The Unspoken Reality Behind the Harvard Gates | Alex Chang | TEDxSHSID

Back in high school, Alex was not exactly Ivy League material. He did not even finish top 5 in his public high school in New York, did not get a near-perfect SAT score, did not win national honors in math, was not a starter on his lacrosse team, and did not have rich and famous parents to get him into places. Therefore, his story of being accepted and completing his education at Harvard College and Harvard Graduate School of Education as an ordinary student served as the prime model for high school students who want to reach their dream schools. However, in addition to sharing his secrets to Ivy League admission, Alex feels the social responsibility to inform—and warn—students about the life behind those Ivy League gates. Things may not always be as pretty as they seem.

Speaker: Alex Chang
Date: April 1, 2017

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at

Who are you, really? The puzzle of personality | Brian Little

What makes you, you? Psychologists like to talk about our traits, or defined characteristics that make us who we are. But Brian Little is more interested in moments when we transcend those traits — sometimes because our culture demands it of us, and sometimes because we demand it of ourselves. Join Little as he dissects the surprising differences between introverts and extroverts and explains why your personality may be more malleable than you think.
