Nothing can boost your energy and spirit like an unexpectedly good news. While body, mind and soul suffer the most from unexpectedly bad news; the element of unexpectedness intensifies the impressions either in positive or negative way.
It is good to be able to keep calm and to realise that when one door is closed, eventually another door is opened. Over excitement clouds the reason and leads to hasty decisions and finally result in stupid actions.
Do not hurt anyone and do not get hurt; this is the basic of all ethics and there is no other main sin if you are religious or wrong if you believe in principles or whatever you like to call it; as simple as that. But sometimes even for decent people is not understandable; I know some highly educated people from a good family that call it unethical if for example you pick a single flower from a garden that does not belong to you but themselves have done unbelievable shameful acts such as disrespecting their parents; planning the inheritance while their parents are on the hospital bed; disrespecting their own mother during her funeral by breaking into room of their sister and stealing money and documents!! and worse exhibiting her bank statement during the ceremony!!!!! just because their mother felt it was unfair the sons receive all the favours such as studying abroad, wedding expenses, cars and expensive jewellery while they had never been grateful and gave her daughter who cared for her parents and lived with them, some part of her own house. And this is a fact that when masks drop, people may behave in such a way that it is both shocking and unbelievable.
