“At the beginning of the day, when you're doing a show like this, you want to entertain and you want people to have a really fun time...but at the end of the day you want them to walk out feeling changed and taking something more away from it...and it's really kind of rare that you get to do that all in the same night.”

“If you really want to focus on something, says Castellanos, the optimum amount of time to spend on it is ninety minutes. "Then change tasks. And watch out for interruptions once you're really concentrating, because it will take you twenty minutes to recover.”

“Because you actually might not know what activities truly engage your attention and satisfy you, he says, it can be helpful to keep a diary of what you do all day and how you feel while doing it. Then, try to do more of what's rewarding, even if it takes an effort, and less of what isn't. Where optimal experience is concerned, he says, "'I just don't have the time' often means 'I just don't have the self-discipline.”

“It's like anything. It's like you're an actor, or a painter, or a writer. You've always got to entertain yourself first before you can even consider entertaining other people. Because if it doesn't excite you, it's never gonna excite anybody.”

“There are days when you don't feel like running. Those are the days you have to do it. Discipline is doing what you don't want to do so you can do what you really want to do. Got that?”

“The problem for a lot of people is that they don't really know what they want. They have vague desire: to 'do something creative' or to earn more money or 'to be free', but they can't really pin down what it is precisely that they want. So they drift from one thing to another, enjoying some moments and hating others, but never really finding fulfillment or success. (..)This is why it's hard to lead a successful life (whatever that means to you) when you don't know what you want.”

“It´s natural to want someone you love to do what you want, or what you think would be good for them, but you have to let everything happen to them. You can't interfere with people you love any more than you're supposed to interfere with people you don't even know. And that's hard, ..., because you often feel like interfering -you want to be the one who makes the plans.”
