So take the time to find the thing that excites you more than anything else in the world. Not the thing your parents want you to do. Or the thing that all your friends are doing. Or that society expects of you.

My key message to her, as a nine-year-old, recently has been, “You don’t need to be friends with everyone, but you’re forced to respect everyone. And everyone doesn’t need to be friends with you, but everyone is forced to respect you.”

Spend your time on something meaningful. Not on parties, and not on taking it easy. That’s not good enough. […] When you’re young, you think: Let’s party, do drugs, drink, waste it all, right? But as you get older, you look at what you’ve accomplished. And when you get old, you’ve run out of time. You have to ask yourself: Why am I here? Can I contribute anything to humanity, to society, my work?

One day, I spoke to him about my sense of shame. He looked me in the eyes and told me that brewing was a science; it was not about getting drunk. He did not stop there. He said: 'Do not make judgment on things, people, and issues with half information.' He said there is truth in everything you see around. So, look for everything in its entirety. That was a game-changing moment for me.

They’re not failures, you try something and it doesn’t work, and some people, you know, get fed up with this, and I’ve known some of my friends and colleagues who have just decided to give up science because they can’t stand it, but I’ve always decided, you know, if it doesn’t work, forget it and start planning the next experiment, and that’s always exciting.
