“I believe that every person is born with talent.”

To Barack Obama, as quoted in The Audacity of Hope: Thoughts on Reclaiming the American Dream (2006), Ch. 5
Context: I happen to have a talent for allocating capital. But my ability to use that talent is completely dependent on the society I was born into. If I’d been born into a tribe of hunters, this talent of mine would be pretty worthless. I can’t run very fast. I’m not particularly strong. I’d probably end up as some wild animal’s dinner.
But I was lucky enough to be born in a time and place where society values my talent, and gave me a good education to develop that talent, and set up the laws and the financial system to let me do what I love doing — and make a lot of money doing it. The least I can do is help pay for all that.

As quoted in Ms. magazine (August 1972) p. 40
Variant: I restore myself when I'm alone. A career is born in public — talent in privacy.

We do not ask sheep to be wolves; we, the wolves, do not ask ourselves to be sheep. Sheep can make such rules as happen to suit them--but it's foolishly naive to expect wolves to obey."
