Optimism is a strategy

Optimism is a strategy for making a better future: Noam Chomsky

In the words of Noam Chomsky...

“Optimism is a strategy for making a better future. Because unless you believe that the future can be better, it’s unlikely you will step up and take responsibility for making it so. If you assume that there’s no hope, you guarantee that there will be no hope. If you assume there are opportunities to change things, there’s a chance you may contribute to making a better world. The choice is yours.”

Or to put it another way, things don't have to be how they are, or go back to the way they were: if we want it to happen, we have the opportunity to create for ourselves a future that's better for everyone.
