I had learned the importance of going at it every day, being disciplined and excited at the same time. I had learned the value of intense focus, and that the more books I wrote the easier it would become. I applied the same thing to doing interviews. You learn by doing, over and over, practicing and practicing. And from this, you slowly get a pleasure, a joy from the process itself and from mastering something. And that joy and that pleasure stays with you for your whole life. It is embedded in your brain.
