To be more precise there is big difference between shameful acts and feeling a shame.


Shall I explain the difference between day and night?


Shameful acts are the acts which are not liked by the majority of people, feeling a shame is the feeling when you fail to do things which you are told to do by your boss.


A kid can feel a shame if his colleagues can dance in a dancing class he can not.


Feeling a shame is useful if it moves you to correct wrong things which you are doing, example not doing what your boss told you is a wrong thing, if your boss blamed you then ideally you should feel a shame and do what your boss tells you so you will not be blamed again.


People who success in this life are people who learn from their mistakes and not repeat the mistakes.
