In 1962, 24-year-old Phil Knight was on an early morning run in his hometown, Portland, Oregon.
Fresh out of business school, he found himself back living under his parents' roof. He also found himself committing to a less conventional career path: pursuing his "Crazy Idea," rather than finding work at a big corporation.
"As I began to clip off one brisk six-minute mile after another … maybe, I thought, just maybe, I need to take one more look at my Crazy Idea," he writes in his memoir, "Shoe Dog." "Maybe my Crazy Idea just might … work? Maybe. No, no, I thought, running faster, faster … It will work. By God I'll make it work. No maybes about it."
