We have been from our child hood has been instructed to always be right.
If you get 70% marks then you are right! but if ou fall short by 2 -3% then you are wrong.
If you complete the work then you are right but, only if there is something even small is pending then you have been instructed many times tha you have not completed work. sometime the 95 -99% completion is ignored and whole focus goes on the 5 % shortage.
Life is not gambling where If you are not pointing in the right direction that mean you are wrong and you will lose the bet.
As in gambling if you don’t get the exact number you bet then you lose it.
But it is impossible to apply same principle in real life.
There is a lot of gray area between winning and losing , right and wrong. The width of gray area depends on the purpose of the work. It may be very short and sometime it may be very long.
