"WHY"

Why the situation arises which we don’t want?
Why we always try to make ourselves happy?
Why we except something from others?
Why we always think we are superior then others?
Why we cannot reach others expectation?
Why we never understand others problems?
Why there is a great difference between success and failure?
Why we always want success in our life?
Why we have to face failures in our life?

All this we can handle but
Why we are having so much of dreams?
