This is a very deep and blunt piece of writing .
I will say uncertainty is another definition of life . we all don't know what to expect even though we calculate and predict .Probably because we are not in control of plentiful things going on around us . 
At the end of the day , We can't control the happening of of events but rather we can control the way we react to them .
