re: ever contemplate what the world would be like if you were never born?

It is a tough thing to evaluate as you automatically focus on the obvious impacts you make through your life, but there are unknowingly countless little things you have done (actions you have taken or avoided) or things you said that could have positively or negatively impacted someone else.

You will never know what these things were, but they likely altered the course of someone else's life and the cycle continues......
