Our business everyday is to make money for people. And I take it as seriously as doctors who are trying to cure cancer, because by giving people financial freedom, we allow them to do great things in their lives - from retire to send their kids to college, to buy their first house, to fund a business that they might want to start.

We need to have mentors. I think I've always been pretty shameless about seeking out people much smarter and much more experienced than me from the very beginning. Michael Seibel and other people.

In fact this poem and “La Maison du Berger” are among the most beautiful poems in the French language, unfairly neglected today.
