Happiness And Sadness are momentarily.

Happiness and Sadness are part and parcel of life. But the most important goal should be to not indulge ourselves into it so much that at times we start feeling lost and depressed. A thing to remember is that to not get attached to things/people so much that living without it/them might seem impossible and extremely hard. We all arrive at a point in life where we are confused about letting go and holding on. Things that are truly meant for you will be yours and things that aren't will never be. No matter how much hard you try to hold on or save, it will eventually vanish. The solution is being a STOIC. Being Stoic is being calm and almost without any emotion. True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient.
