For some time now I have been aware of the power of perspective and the choice we have each minute to focus on something good or to focus on something bad. We have the choice because we are surrounded by so much good and so much bad. I don't normally blog on this topic, but this time I couldn't resist. Most examples I've read about or personally experienced on the optimistic perspective have a small or narrow context. But here is a person who has applied optimism to our global problems. Oh, and he mentions 3d printing! Well worth a watch!
