It is true. "Change me when you are perfect."
Whatever you do to others, you are not doing it to them, 
you are doing it to yourself.

When you love others, you are not loving them, 
you are loving yourself.

When you hate others, you are not hating them, 
you hate yourself.

When you are happy, you are not happy with them, 
you are happy with yourself. 

If you do not want something to come back to you, 
don't send it out.
Do not forget that there is a price for everything.

So if you do not want other people to judge you, 
don't judge them. 
If you do, they will.
