look up anything, like your first name:
1. not giving a fuck
not giving a fuck is not a matter of how MUCH effort is put into something, but rather how much one CARES about whatever amount of effort they happen to have put into something.
For example:
man 1 can work hard all his life and make millions and literally be not giving a fuck about what has happened in his life

AND
man 2 can be homeless and mope and be sad about his position in life, therefore he fails in not giving a fuck and in this senario he is the "loser"

As opposed to the common misconception that man 2 gives less of a fuck because he hasn't worked a day in his life.
2. Not giving a fuck
Bliss.
Man, your definition is the rape of the concept of happiness! Not giving a fuck is living by the day whilst being yourself!
