I learnt this a long time ago, to stay away from negative people. Earlier, I used to let a lot of people stay rent free on my mind and this used to trouble me a lot. Nothing affects me more than humans and it is a known fact that people continue to be my nemesis. I have met so many people in my life. While some bring joy where ever they go, others can create chaos in the calmest of places. Negative people are of different kinds. Pessimists are not the only negative ones, there are many many more out there.
