The first time I was ever impressed with Patagonia as a brand was when they released the 'Don't Buy This Jacket' campaign. That campaign highlighted their understanding of their role in a larger environmental justice space.

I have a big following on Twitter, and Twitter has been invaluable for mobilizing and quickly sharing information. But I'm not really sure that people are learning deep content on Twitter.

I am mindful that the goal of protest is not more protest, but the goal of protest is change.

While I've done over 10,000 heart operations and invented operations and devices that are used every day in heart surgery, the joy I receive from watching even one person take back their health just can't be surpassed, and certainly can't be measured monetarily.

What we've been finding is people are afraid of happiness. They're afraid of happiness because they think we'll stagnate or we'll be blind: that if I'm happy now, I won't keep fighting as hard. If I'm happy now, I won't push as hard to make a better world. That's what pleasure does. Joy does the exact opposite.

The greatest happiness of the greatest number is the foundation of morals and legislation.
