make the world a better place

How do you measure this? At what point do you go ‘ok I’ve accomplished my goal, I’ve made the world a better place’?

I recently watch a movie called ‘The life of David Gail’ and my heart is broken. I cant believe things like that go on in real life. My path in life is set to make the world a better place. I’m not really sure how to do this but I have a feeling it starts with the small things. Like helping the old lady cross the street or making sure that youngsters know there address and phone number in case of an emergency. I am committed to doing what needs to be done.
