Why so many doubts ?

It is all right (!) to question, but does it not hold up ?
Leaders are those who just believe. But is this belief beyond doubt ?

Anyway, to do anything, you have to move ahead based on premises.
In the early evening of life, I begin to doubt the very benefit of doubt !

So, inaction is no solution. Action needs an assumption. Justification in retrospect is - well , I did the best based on the information and knowledge available at that point in time.

Is this good enough ?

Little Swati tells me - you can't stop thinking, thoughts flow in all the time !

So correct !
