The future belongs to optimists..some say. Certainly optimists have a very attractive energy. But also we know that optimists can be potential pessimists who are too stupid to read the signs. An optimist in 1930s Germany was blind. So being a useful optimist also involves being perceptive.
Look hard for things that really are getting better. Find something you can be optimistic about. Find a good place to do it. Do a lot of it. Make the future.
