never be too sure

Never be too sure of yourself. Never believe that you are right. You might (most probably will) be wrong.
whatever follies you point out in everyone else might be present in you as well. its just that nobody pointed them out. and if they did you never believed.
We all look at this world with us as the centre of the universe. but have we ever tried to have a bird eye view of the situation? It's very difficult to take your perspective out of the scene. but that is the only way that you can do justice with yourself.
And it so happens that each and every person in this world has a picture of the world where he is never wrong and everyone else is. and there are some fortunate people who are not aware of this fact that everyone believes that he is perfect. and these fools actually think that they are perfect in the absolute picture as well. kya karein computer vision nahi karte log achhe se. perspective ke funde wahin se clear hote hain :P.
So anybody who knows that he can be wrong has solved half the puzzle. The rest is up to him. Just like someone who knows he is a loser is not a ccmplete loser anymore. Now whether he wants to fight back or decides to stay loser is a matter of choice and priorities. And yes, we do not doubt abilities here. But the problem is when someone does not know whether he is a loser. By the way we all are a bunch of losers.
And waise bhi its not the external reality that makes someone a loser. A man is loser inside his head. And there is no way anybody else can know whether I am a "loOser" or not. And if I were, I would be proud of it :D.
