Yes it is!
It absolutely is!
It definitely is!
To expect of brighter day after a dark night
To expect happiness after sad happenings
To expect win after a lot of struggles
To expect appreciation after hardwork
To expect all this is wrong
Since one should not expect!!
Expecting is wrong!
Do your karma and forget the result!
This what is expected from you!
This is what you should do
And this is what is not wrong!
