There can be many ways to do a thing correctly..
There can be many ways to commit blunders too on the same issue..
Still we tend to assert that the way we did something right is the only way it should be done.
Of course we are generous in choosing ways and means to commit blunders..
I think life will be smoother if we can accept that there are many ways to do something right and many more ways to commit blunders..
Great philosophers and leaders alawys understood this.. although many would have not acknowledged it openly..
But a fact is just a fact whether you or I accept it or not..
