Trying to become a better person.

we can impove upon our personal behaviour , communication skills , +ve attitude, by working for betterment of others and society. By doing good things

Changing your minds with the world,that's enough.

In order to be a better person, you must first define what "better" means for YOU. One of the problems that I see in society is that people are judging others based on a canned set of definitions for concepts that only have a subjective definition. Being a better person in the desert means finding and sharing water. Being a better person in downtown New York City might mean stopping a crime. I think that to be a better person you must first define what better means for you as an individual, and then set specific goals that will take you in that direction.
