When Thales of Miletus lived, there was a proverb to the effect that the poor philosophize because they're poor and have no recourse to feel better. Thales, a philosopher, took a bet that he could get rich quick.

He got rich and told his peers, he still doesn't care about money as he has more important things to do, such as philosophy.
