Because of different mental attitude

My friend Zuwaina Al-Harthy has shared this with her fellow relatives and friends on Facebook, and I'm blessed to be one of them.

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 it.

example .. two people may be in the same place, doing the same thing, both may have about an equal amount of money and prestige and yet one may be miserable and other happy.

why? Because of different mental attitude.
