Uncertainty .

What is Uncertainty ?, I googled it and Google gave some recursive definition that is hard to comprehend, its not google's fault I am bad at comprehending. Well then I will not define it in words, I can at least feel what uncertainty is. 

I believed uncertainty is frustrating, it definitely is but lately I have started seeing a different side to it, its importance and how life is a function of it. Uncertainty throws challenges at me, makes me numb sometimes, takes away breath from me, make me feel happy/sad/angry and what not. 

If everything was certain, will we feel the emotions in the same way ?

I have a thought that If life was not uncertain, we human will be efficient at what we do ?

Will life make sense if everything was decided like some Janam Kundli but way more precise and detailed ? 

can we achieve certainty in life ? 

I am just trying to think and ask questions, I mean this is something I should have been doing all the way through life, but someday is better than never.

Though there is no way someone else will be reading it but if someone does .. Try to answer these questions based on your perspective .
