"Nobody can take away your pain, so don’t let anyone take away your happiness." – Unknown
You need to be able to be perfectly happy just on your own. If you ever want to be truly happy you must be conscious of the fact that you determine your happiness and not anyone else. Never let someone steal your happiness, it was never theirs to take. Life is full of ups and downs. The trick is to enjoy the ups and have courage during the downs.

"It isn’t what you have, or who you are, or where you are, or what you are doing that makes you happy or unhappy. It is what you think about." – Dale Carnegie
