As a rule, we see what we want or expect to see. Some see the glass half full, while others see it half empty. It’s the same glass. Only the perception has changed. So why not choose to see the similarities that we all share rather than the differences? Again, it’s the same people, only the perception has changed.
I agree, we do see what we want to see. All of us think differently so that’s where our problems lie. But similarities can be the thread the unite us.
