in a world where only a minor portion of the land is really well suited to agriculture, man is using much of the best land with dubious efficiency.

Hope is a stance, not an assessment.

Each of us carries within us a worldview, a set of assumptions about how the world works - what some call a paradigm - that forms the very questions we allow ourselves to ask, and determines our view of future possibilities.

What we need to get right is not focusing on the fear associated with quantity - not enough, scarcity, and lack - and moving instead to a worldview that explores quality and connectedness.

I had no identity [when I was 27] - I was terrified that somebody would ask me what I was doing, and I would have no answer.

I also believe that it's almost impossible for people to change alone. We need to join with others who will push us in our thinking and challenge us to do things we didn't believe ourselves capable of.

We evolved to be problem-solvers, to create, to be choosers of our own future!
