In the early days of my first startup, PlanGrid, our cofounder Antoine Hersen—who was only 29 at the time—died of cancer. We lived and worked from a house in Sunnyvale together, and he programmed until his last days.
Before he passed, Antoine gave me his copy of by Seneca, and inside he included his last letter to me: “Life is short. Take care of Ralphie. Don’t be afraid to try new things. Never do anything that makes you unhappy.”
