the thing about sadness
There is a unique difference between sadness and melancholy. Everyone gets sad–it happens all the time. But for some reason, several people seem to be more sad and depressed compared to others – if that's even the case at all. In truth, the duration of sadness does not translate with a person having a more sad emotion. It is true that you feel sadder to lose someone that you care about, compared to losing a random accessory that you possessed. But that is only the cause and effect of how much a person cares each subject, which may have a certain correlation on the duration of sadness for a particular threshold. However, the main reason that some people are in a sad situation for a long period of time, is that they are behaving melancholic: the state in which a person voluntarily and repeatedly grasp on a notion of sadness over and over again. This practice is undoubtedly what causes a person's life to be miserable–for he/she is voluntarily ignoring any path towards happiness through any positive emotions. So it is obviously pointless to be overly melancholic of one's sadness. Keep your mind positive and carry on with your exciting and adventurous life!
