One of the best pieces of advice I ever got, back when I was 23 and newly out of school, is this: look around and figure out who you want to be on your team. Figure out the people around you that you want to work with for the rest of your life. Figure out the people who are smart & awesome, who share your values, who get things done — and maybe most important, who you like to be with and who you want to help win. And treat them right, always. Look for ways to help, to work together, to learn. Because in 20 years you’ll all be in amazing places doing amazing things.
Couldn’t agree with this more. The core group of friends I made at my first start-up have all gone on to great and interesting successes.
