Everybody else is afraid to fail. I do not really care because when I fail, I try something new.

Every big problem is a big opportunity.

Is it 10 years, 20, 50 before we reach that tipping point where climate change becomes irreversible? Nobody can know. There's clearly a probability distribution. We need to ensure this planet, and we need to do it quickly.
