As a cancer survivor, successful entrepreneur, and battle-hardened business executive, I learned many valuable leadership lessons. Take cancer for example. I had never been sick a day in my life when I was diagnosed with cancer at age 34. I was at the height of my mental and physical prowess then — invincible, confident, independent. I’d out work anyone, try harder, work longer with more effort to achieve any goal I set my mind to achieving.
I was also egotistical, naive, shortsighted, and woefully under supported.
