For in every ill-turn of fortune the most unhappy sort of unfortunate man is the one who has been happy
BoethiusNothing is miserable unless you think it so; and on the other hand, nothing brings happiness unless you are content with it.
BoethiusBalance out the good things and the bad that have happened in your life and you will have to acknowledge that you are still way ahead. You are unhappy because you have lost those things in which you took pleasure? But you can also take comfort in the likelihood that what is now making you miserable will also pass away.
