A case for appreciation
Life comes with a great number of difficulties, but also a great number of good things. We need to be able to appreciate the good things in life without waiting for everything to be perfect, like being able to appreciate the beautiful trees in a forest even if one of them is sick.
Given the probability of having such an experience for an element in this universe, we are "lucky" to have this human life. To find happiness in it, we should learn to appreciate its good sides. The sun, water, colors, flowers, trees, birds singing, good food, nice smells, music, passion, kindness, friendship, love...
There is a certain share of bad luck, more or less depending on the individual, but I think that everyone should find a way to appreciate the good things they are lucky enough to experience when they can, no matter how small they are.
Society as a whole should also, despite all the negative news and without forgetting what is sometimes necessary to improve things, recognize the things that are good. It is much healthier for the whole that way.
