X. We Are Grateful For Everything, Entitled To Nothing

This core value comes from Jack Clark, head coach of the Cal men's rugby team. Since he took over the program in 1984, Cal Rugby has won 22 National Championships (through 2013). Beyond winning, Clark does a really good job articulating his approach to building a high performance culture. Jen Sinkler did a great interview with Clark for her website. Here's a section:

Our mindset is how we filter our values and how we talk about them. I think it’s important now, more than ever before, because there is a lot of entitlement. But we say our mindset is “entitled to nothing, grateful for everything.” We’re really happy when people do something for us and somebody washes our clothes or somebody puts on a meal for us. Anything that we get, we feel really grateful for it but we don’t really think we’re entitled to much. I mean you ask how do you become resilient? Well, that’s
kind of it. I mean, you don’t expect much — not from the ref, not from the opposition. If you’re playing into the wind in both halves, that’s just how it is. We just don’t expect to get a break. That makes you tougher in a way. We don’t spend a lot of time worrying about what happened to us and why did it happen to us and woe is us. We just get on with what’s the next most important thing, which is our definition, by the way, for mental toughness. We borrowed that definition from a really good Australian cricketer. I always thought it was the cleanest definition of mental toughness I ever heard.

And here's Clark speaking at Brett Ledbetter's What Drives Winning Conference in 2015:
