When you wake up sore the next day after a workout, you know that you did something worthwhile. Your body is healing--and you feel it. You also probably feel good about it (as long as you didn’t hurt yourself.) Soreness and discomfort mean we are doing something right. Who really wants to send one more email? But we do--we stay up late, we push ourselves beyond what we think we’re capable of. We take on the persona of a mad scientist who sees what others do not. And we work to make that vision real through the awkward first emails we send to sponsors, through the people who tell us our work (or we ourselves) is nothing, and through all the pain of the many mistakes we make with business and with people. Cherish discomfort.
