If you just added me to your circles and are wondering why I'm not circling you back right away.... It's because I can't have 4,000 people in my stream. If you're brilliant in comments and don't post I'll still circle you. If I've circled you and you're not much interested in my posts no biggie; leave me out of your stream.
I am a pessimist. If your world-view is unicorns-shitting-rainbows block me now.
Anybody left? Good, we can get to work because optimists don't seem able to make a roof that doesn't leak or a foundation that sits above the water table instead of under it. Optimists build cruise ships that flop over and sink when holed. Optimists design economic structures that collapse like a house of cards in a slight breeze.
We have to build a better world than the optimists will let us build. A world that expects that rain falls at inconvenient times and deals with it. A world that deals with climate change and ecological overshoot. A world that deals with people as we find them instead of as we wish them to be.
