Blurred Trajectory of Joy...

I often think or rather ponder that why would something which every human is relentlessly trying to achieve is so oblivious and not so ubiquitous or perrenial.
The thing which I refer to is the thing which should be the premise of our act like life ,instead it comes in interludes.
Forever we humans have tumbled to carry the miniscule burden of happiness. Happiness has been disguising itself in the form of joy, mirth, laughter and million other forms. Still we have not been able to hold on to it in the gleaming light of life. We have often been connoisseurs of falling with happiness whereas we should have been rising.
Momentary bleaks of happiness is all that we can manage on the trampoline of living. We carry sorrow on the flip side with grotesque panache, flaunting it all over the land. Even the herculean weight of despair seems feather like to us and we carry it without a frown, as if we existed to lift mountains but dropped of pebbles like delinquents.
Although , Rousseau said that 'I walked a mile with happiness neither a word said she, but the things I learnt when sorrow walked me' , I get puzzled with the stoic silence of happiness. Why can't we get ourselves to learn from happiness? Why can't we swing away with mirth? Why can't we dance with joy forever? We manage to do volce with sorrow more often than not ,don't we?
Is it not to be drawn by us, the trajectory of joy. Will it have to be blurred even if we tried to follow it with strength. A small effort to lift happiness and strut with it around would do more good than bad for sure.
