"Only once one has known real sadness can one feel true happiness."

We can rephrase this by writing -' we understand the true worh of something only once we have lost it'. Not conveying particularly the same meaning but somewhat similar both phrases signify that we have to go through something unpleasant in order to understand the worth of our happiness. The statement, Only once one has known real sadness canone feel true happiness is thus justified.

People who have been through tough times, have seen the dark side of life can appreciate true happiness at its best compared to those who consider it only inevitable and something they don't really think they do not deserve thus undermining the true value of happiness. For example, we have a rich businessman's son who has always had the biggest luxuries at his beck and call would not really value or understand the happiness of getting a new swanky car of which he would probably have many in his garage. Ask a middle class worker who has seen the darkest of days when he probably had to work overtime to enroll his kids to a school, for him getting a new drive would mean happiness not only for him but his entire family which for him would be something very valuable.

Thus there are testing times which require us to be thick skinned and put up a brave front but it is only after we have been through our share of hardships can we feel true happiness. As said by a great poet, "when winters come, can spring be far behind?" It is very important for one to know real sadness, to desperately long for happiness in order to actually, truly feel the happiness when it finally hails. Another example can be a student preparing for exams, only once he has known sadness in terms of sacrificing movies, parties with friends etc. to study hard, can he get the true happiness of getting good grades and possibly admission in a reputed College of his choice.

The sadness is what makes us realize the importance of happiness. Had we been happy all the time we would take it for granted and would not value it enough. Sadness makes us realize the balance in life. The negatives and positives. As in maths two negatives always add up to positive
