The good life may mean doing some things that do not feel comfortable. It may mean sitting long hours just with yourself as you begin to listen to your own questions. That was the reality for me when I was 27, and it was really terrifying.

My children threw me a life line: "Return to your roots - food - and rewrite your first book, Diet for a Small Planet." I learned that if I could just show up, in this case, if I could just get myself out of bed, get to the computer in my tiny office at MIT, and start writing, help would start arriving.

Making conscious choices about what we eat, based on what the earth can sustain and what our bodies need, can help remind us that our whole society must begin to balance sustainable production with human need.

There are surprising turning points; there is the straw that breaks the camel's back, and you never know if your action could be the straw.

I don't rule anything out, and I couldn't underscore more the importance of what YES! is doing to show that there are people who are pushing the edge of hope, who are stepping into the unknown and taking risks, because that will then enable others to do the same.

Honest hope has an edge. It's messy. It requires that we let go of all pat answers, all preconceived formulas, all confidence that our sailing will be smooth. It's not a resting point. Honest hope is movement.

I've grown certain that the root of all fear is that we've been forced to deny who we are.
