Charitable Habits
When John D. Rockefeller started his first real job as a bookkeeper, he established a habit to give a portion of his earnings to charity. Despite his greed, he continued this practice for the rest of his life. Often times, his charitable donations were substantial, but he also carried around nickels and dimes so that he could personally give money to strangers and friends.
He was known for carrying a pocket full of dimes for this reason, and he was also known to give them to his fellow rich business moguls. He would often give the coins to prominent men like Henry Ford and Harvey Firestone, both insanely wealthy in their own right.
