‘…the most useful definition of creativity is the following: people are artistically creative when they love what they are doing, know what they are doing, and actively engage in art-making. The three elements of creativity are thus loving, knowing and doing; or heart, mind and hands; or, as Zen Buddhist teaching has it, great faith, great question, and great courage.’
Loving, knowing, doing. The secret behind becoming excellent at anything is loving one thing deep and hard enough to do it for a very long time. To continue to learn and know it.
That's Eric Maisel via Justine Musk, in her epic post on why you have to read like a maniac to develop a writer's intuition. Later she says:
Don’t just read because it will make you a better writer – although it will. Read because you love to read, you love stories of all shapes and sizes, you love the flow and rhythms and innovations of language, you love to learn stuff about people, you love to learn stuff about the world, you love to form relationships with individuals who don’t exist. Read because you love to write. Read because you love fiction and nonfiction and their pirate chests of treasures.
