PERCEPTION meaning, "the way in which something is regarded, understood, or interpreted".
We live in a society, full of people with different Perception of yours. Some may think you are best person, other may think you are the worst and deserve to die as soon as possible. Some may think you are Heterosexual, other may think you are gay. Some may think you are have a good stable job, other may think you are a gang leader.
The point here is you are unique in your own way and perception other are having about you should not affect you in any way. 100 people, 100 perceptions and it's the same in every corner of the world.
