can’t I just exercise past my bad diet? Won’t an extra ten minutes on the elliptical trainer solve everything? Amateur Finnish triathlete Sami Inkinen tried and failed. Sami was one of the original founders of Nokia, sold his share early, and moved to the US to attend Stanford Business School. There he started the real estate website Trulia, which was bought by Zillow for $2.5 billion. In other words, Sami had more money than God—and he exercised five hours per day.
