If you look for the bad in people, you will find it. Whether it is real or just your reality does not matter. But what does matter is the level of effort it took for you to look for it. Why waste time on looking for the negative when there is so much negativity that already exist around us?
Bad, negative, and waste are all words that over shadows the words good, positive, and productive. Why not use the time and effort to find the good and positive attributes in people? That would be more productive and rewarding for both people than wasting time and effort looking for darkness in ones character. For every bad find two goods..... Stop convicting innocent people and start convicting your own negative thoughts and views. You just might realize that you have pegged some people all wrong and they are actually good.
