I found Rockefeller to be strangely stoic, incredibly resilient, and, despite his reputation as a robber baron, humble and compassionate. Most people get worse as they get successful, many more get worse as they age. In fact, Rockefeller began tithing his money with his first job and gave more of it away as he became successful. He grew more open-minded the older he became, more generous, more pious, more dedicated to making a difference.
