Hi Jason. A few years ago, whilst raising money for a local animal sanctuary, I found that for every kind hearted soul there were 20 people who really did not care! And, as you have said, dealing with an uncaring person will encourage you to feel more negative and this in turn will affect your mood for the rest of the day. I tended to try focusing purely on that one kind person I would encounter, thinking to myself that if everyday I was able to meet at least one kind person, that would be a good day. If I spent 2 hours dealing only with people who didn’t care, I would still keep up my positive attitude in case the next person I spoke with was that one kind soul! This way I found that I generally kept quite positive and this led to each day being more successful and I would find many more kind folk than just one 🙂
