Does someone get you coffee? When you go somewhere, are you treated well? Do you have perquisites of your job or profession? Sometimes, we have good fortune, and are treated well, and we expect it to continue forever. Then, when all of the good things are taken away, we are shocked. Entitle people always are more affected by a change in fortune. But, fate is fickle, and she gets us all in the end. The Stoics prepared for this eventuality by reminding themselves daily that we are entitled to nothing, and that we are lucky when we are lucky. We are not when we are not. They called it: "Premeditatio Malorum", which is Latin for remembering that bad things will happen sooner or later. The old saying "the bigger they are, the harder they fall" can be prevented by this Stoic principle. It also reminds us to be humble when good fortune comes our way. Hey, give me all the good fortune you want, Fate. I will still remember that bad fortune is just around the corner. And, I'll be ready.
