Optimism vs. Pessimism

"Optimism is the madness of insisting that all is well when we are miserable" - Voltaire 

All of us have had our share of bad days. Yes, the worse ones too!
So what do you do during these times, turn to happy faces at work, have a chat with ever cheerful siblings or just a dose of pep talks (read crazy) with buddies?
Ever wondered why we consciously or unconciously choose so?

Its because these are the people who have the power to lighten up, boost up, spark up and spread some positivity! 

All you need is a little..little...bit of optimism. Thats it! 

Think a bit before you speak! It can brighten up some one's day :)

P.S.
Typical characterisitics of Pessimists are excessive usage of what if/no/but then/indecisive/inconclusive talks. Beware! They can cripple your system!
