Sadness.

Aha. So I would have caught you thinking,'why include sadness in this place?'
Because sadness too is required.Only when we are sad, can we enjoy the happier times better.
As then, we would know the value of happiness & joy, something we all take for granted.As the lines of a popular song go 'you only know you've been high when you're feeling low'. Now be true to yourselves.We do take it for granted that we will always have a happy ending for everything, do we not?.

Sometimes we become sad, we cry without reason. which is good, as it releases pent up feelings. Feeling sad can help us introspect and improve.Sadness is not a sign of weakness or sensitivity, it is a sign that we are alive and have emotions and feelings.

That doesn't mean we be sad most of the times! Because we need to move on in life, bettering ourselves.Only when we know the reason for our sadness, can we find a solution for it.And to tell you the truth, we can't remain sad for long!So we better not spoil our moods at special times (yes I'm contradicting myself) due to petty things.

sadness to sadness to sadness to happiness!
