I'm close to your age and I'm excited for the next 40-50 years. It often surprises me when I get perspectives like yours. I have to remember people have different opinions on things I take for granted.

We can have a tendency to project our views onto everyone else and assume everyone thinks the same thing. False consensus effect

I think people are fundamentally different because of some stuff that happened in childhood. There are people who are negative about the past and positive about the future. I fall into this.

There are others that are positive about the past and negative about the future. Maybe you're here.
