(4) Ups and downs
You wish to be happy all the time. It’s a general wish that all mankind shares. Is it possible, though? Hardly. Is it a tragedy? Not really. Why? Simply because being human means experiencing all the ranges of feelings according to the experiences everybody is given during their lives. Besides, you can enjoy happiness, or any other feeling, only if you have knowledge of its opposite. If you like being on a mountain top, would you want to stay there forever? You probably wouldn't. The lower land, too, has its positive side: going down you might stumble on some rocks, but your walk will make you feel more active. Therefore, up you go... stay and enjoy the view. Down you go... move and enjoy the walk.
