The future is uncertain. Always has been and always will be. We are each of us approaching the grave. No way around it. On the other hand it has never been easier to have fun along the way.
I am personally optimistic because I see ways I can make my own life better. Facing uncertainty and adversity will happen no matter what. There’s so much to do and so many wonderful things in this world it doesn’t make sense to focus on anything bad.
When I think of restons to be optimistic I just remember that the world is what I make it. To have a great future I just have to make it happen. I’ve done a pretty good job so far.
