I’m 42 years old. I’ve been an entrepreneur exactly half of that time, opening several successful businesses en route, and lately, I’ve done a lot of reflecting on how I’ve managed to survive this long. You tend to get more philosophical as you age, but that’s not the only reason for my musing; I’m also the father of six smart, energetic girls, the oldest of whom is in high school and brimming with career ambitions of her own.
