Why is it easier said than done? Because at the moment when people promise, many of them sincerely believe that they will fulfill their promises. But time passes and a lot of circumstances arise that hinder and impede, the causes of all. It is said that the one who wants to do is looking for a way, but who does not want - is looking for a reason. And the problem is that many people do not know how to say a hard "no", which then they suffer either themselves or their reputation.
