Perception

1- what is perception?

The way you think you are from the inside, but it's not the same at the outside. Like a wise man said " you're not the same thing as the inside and the outside" said by Youssef Tamara.

2- why do you the things the way that you do?

Because the brain is like the masterpiece or the king or the leader of the body, it is the controller of the body, no matter how was the action harmful, bad, nice, disgusting ...

In the end the way you're brain thinks is the way you think about yourself, and about everybody around you.
