I just turned 30. As someone who suffers from time anxiety, I thought it would feel the usual mix of stress and depression I usually experience around birthdays. But, somehow, this year is different. I feel calmer, more confident, and more excited about the future. To some who are younger than me, thirty years may seem like a lot. To those who are older, it may seem like not that many years at all. There is still much I want to explore, but I wanted to celebrate with a list of the most important lessons I learned in those few years I walked the earth.Anne-Laure Le Cunff (ex-Googler, entrepreneur, and part-time neuroscience student at King’s College).
