Optimism is good, actually
I get it - it's hard to see good things happening in the world today. Hard not to be cynical about the world, about people, and about our future as a species. There is a lot to be worried about, and the world is more chaotic and unpredictable than ever.
Despite all of this, I choose optimism. I choose to hope that humans can be better, imagine a world where things can be greater than what they are today, and work hard to create a world where new and exciting things are happening for all people, every day. This extends to big ideas, but also to every day things, too.
Try it. If you think something should exist in this world, make it exist. If you want something to be better in this world, work to make it better. You will be astounded with how much it changes your outlook.
