Craig Ballantyne, reflecting on his life, quotes Steve Jobs: “You cannot connect the dots looking forward; you can only connect them looking back.” Connecting the dots in his own life, Craig observes, “If you had told me when I was 18 what I’d be doing at 40, I would have looked at you as if you had two heads! Helping people on the internet, making workout videos and sharing them online, writing web articles about the science of exercise – none of these options existed a generation ago.” Today they’re how he makes his living.
