Yes, you...

“I don't know what good it is to know so much
 and be smart as whips and all if it doesn't make you happy.”
― J.D. Salinger

Everyone seeks happiness in the world and there is ONE best way to find itby controlling your mind.

Happiness doesn't depend on what's happening 'out there'. It depends on what's rattling around inside your head. We are all as happy as we can be if we WANT TO BE. 

Be POSITIVE in thought and deed.

“Happiness is a perfume you cannot pour on others without getting some on yourself.”
― Ralph Waldo Emerson
