“I don’t care how good you think you are, or how great others think you are—you can improve, and you will. Being relentless means demanding more of yourself than anyone else could ever demand of you, knowing that every time you stop, you can still do more. You must do more. The minute your mind thinks, “Done,” your instincts say, “Next.”
― Tim S. Grover, Relentless: From Good to Great to Unstoppable
