I does makes a great difference in life when we think positively on the situations we face everyday.

 

It is just the same as when one chooses to be happy even if the situation or the current plight of a person does not seem so good. 

I then agree when whoever said it that happiness is a choice.

Like there are those deaf and mute people who should be living very sad, but then it is just inspiring that they are happy and contented. They are happy inspite and despite of their situation. so yes, happiness is a choice.
