Following etiquettes is absolutely essential in professional life but as far as personal life is concerned, live life breaking all the rigid rules. Live with flexibility. God has sent you to the earth to live a life which you should live as per your desires. Living life by making compromises is fine to some extent but this should not be a regular thing happening with you. I have seen people are ready to follow telephone etiquettes but rarely bother to get adhered to toilet etiquettes. Everyone is breaking rules so why are you so serious and honest.
