My nagatave thots are more bigger than my posotove thots most of the time?

I notice that I have to fight my first thoughts that come to mind that are negative instead of thinking positive at first. It's like I have to fight through the thoughts and catch myself being negative. I'm a pretty happy positive person that has to work at maintaining positive conscience. Does this make sense? Is it true that we live in a negative world? Or have I been domesticated to thi nk this way..right away? and also my neybors are not going to be ok couse i am gonna get them/.
