can any one explain .......?

Well, that means how positive amd negative a man thinks.Optimists are positive thinkers and see the positive side of the episode and vice versa for pessimists.An positive thinker is bound to overcome all hurdles in life and head towards prosperity and that way he counts his blessings.An nigative thinker always sees the dark side of the situation and his ability to perform his best shatters and that way he keeps counting the discounts in his life.
