Michelangelo painted the ceiling of the Sistine Chapel with one stroke of his paint brush at a time. It took him four years.
Herman Melville wrote Moby Dick by putting one word after another after another. It took him a year and a half.
Nothing just happens. Masterpieces don’t just fall out of the sky. In retrospect, a genius is often someone with a singular focus who just worked a lot harder than everyone else.
