Why I am laughing

If you see me laughing,
It is because I am happy;
And if I am happy,
It is not because everything
Is moving well;
It’s because I have decided
To be happy;
Happiness is a decision;
You decide to be happy;
And you decide to be sad;
No one makes you sad;
And nothing makes you sad;
You make yourself sad;
And you make yourself happy.
As simple as that;
Think about it.
And from today,
Don’t make yourself sad;
Always make yourself happy;
