Reading this article reminded me of the day my father and I built a baseball diamond on the front lawn of our ballpark-sized front lawn. Sure, he did the heavy work, but I was involved in the design and made sure there was a pole for the flag (which would fly over innumerable baseball games through the decades that followed). Not everybody needs to be a full-on design thinker the way I am - the world also needs people who do things like take measurements, check facts, and apply rigor. But everybody probably needs some, and people like me need a lot.And, as John Spencer says, "All we needed was a little freedom, some encouragement, and a few random supplies. And time. Tons and tons of time"
