Before stepping into the ring, Cus D’Amato would repeat to Mike Tyson that you don’t exist, only the task exists. The moment you internalize what this really means, all self-doubt simply ceases to exist, because there’s no longer a self to doubt. What’s left is total immersion in the task, which is what the flow state actually is, where there’s no “you” left to interfere, and action arises by itself, like second nature, faster than conscious thought, through the sheer genius of your unconscious mind.
