If the world's human population had the sa me personality like me, it probebly won't survive for very long.
Progress will be slow because the world will be depressed.
There will barely be any reproduction since no one will have the guys to approach the opposite gender…
But on the other hand there will be 0% crime and no hatred…
so humanity won't survive for very long but it will have a good time…
so how the world would look like if everyone had the same personality you have?
