This is one of my favorites. People think of creativity as this sort of unbridled thing, but engineers thrive on constraints. They love to think their way out of that little box: 'We know you said it was impossible, but we're going to do this, this, and that to get us there. '
I have gained and sustained my optimism as a humble student of our living universe, our living Earth, which clearly shows us the way out of our adolescent crisis into a mature global future. The sooner we create our vision of all we desire, set our intention to implement it together, and put our individual capacities into collective action, the greater our chances of success.
