Nice to see so many familiar names on the Tech 30 under 30 list, congrats to Dan Siroker from Optimizely, Anthony from Kaggle and Darian. (Disclosure: I was on the list last year).
Being on the list is not, itself, a real accomplishment.
Building the business that gets you on the list is an accomplishment. After that, getting picked just means you know the right people. It's a derivative accomplishment that, on its own, has zero meaning or value.
Be proud of the thing you built, not the social noise surrounding "cool kids" lists. Who gives a shit? Do something cool, and take pride in that.
