Human Beings are not perfect.
But seeing perfections in people can make you perfect.

Nobody is perfect.
You too are not perfect.
The world is not perfect.
But, seeing the positive nature of people can make you perfect as an individual.
The vibe of positivity is needed by everyone in this era, where competition is much as high as criticism is becoming the major characteristic of an individual. 

The world is not supposed to change suddenly unless one by one, every individual take their responsibility to be the source of positivity.
