Fruit of labor and thought

"Men give me credit for genius. All the genius I have lies in
this: When I have a subject in hand, I study it profoundly.
Day and night, it is before me. I explore it in all its
bearings. My mind becomes pervaded with it. Then ... people
are pleased to call [the effort that I made] the fruit of
genius. It is the fruit of labor and thought."

-- Alexander Hamilton
