Luckily, I got at a very early age the idea that the safest way to try and get what you want is to try and deserve what you want. It's such a simple idea. It's the golden rule so to speak. You want to deliver to the world what you would buy if you were on the other end. There is no ethos, in my opinion, that is better for any lawyer or any other person to have.

No. Go for it, as I did it. Go for all the mistakes. I made so many mistakes in doing my films. They all have a stutter or a limp or they are squint-eyed. Hardly anyone notices it, but I notice. Make your mistakes. Get arrested if you trespass. Yes. Do it. There’s nothing wrong with spending a night or two in jail. I’ve done that. Don’t be afraid of the grizzly bear behind you. Travel on foot. Read books.

My grandfather looked at me, and after a bit of silence, he gently and calmly said, “Jeff, one day you'll understand that it's harder to be kind than clever.”

It’s a very interesting and challenging field! It’s important to study math and science throughout high school and college, and major in some technical area. Take advantage of all of the opportunities that colleges provide, including professor office hours, tutoring, student chapters of organizations like Society of Hispanic Professional Engineers (SHPE) and Society of Physics Students (SPS), and project-based hands-on classes.

The friends with whom I sat on graduation day have been my friends for life. They are my children’s godparents, the people to whom I’ve been able to turn in times of trouble, people who have been kind enough not to sue me when I took their names for Death Eaters.

So why do I talk about the benefits of failure? Simply because failure meant a stripping away of the inessential. I stopped pretending to myself that I was anything other than what I was, and began to direct all my energy into finishing the only work that mattered to me. Had I really succeeded at anything else, I might never have found the determination to succeed in the one arena I believed I truly belonged. I was set free, because my greatest fear had been realised, and I was still alive, and I still had a daughter whom I adored, and I had an old typewriter and a big idea. And so rock bottom became the solid foundation on which I rebuilt my life.
