Garbage Truck of Negativity

I can't admit I came up with the idea behind this theory because I didn't, but I liked it enough that I thought I'd give you the down low on it because its something that has been good reference for me at times. The thought goes like this: we all know that there are several times in our lives when people have upset us and we have upset other people in the same way. Well one way to become a better person and not let that negativity engross our everyday lives is to look at negative feed back and agree people as a garbage truck. I'm sure your telling yourself that's crazy but its just a metaphorical way to take an outlook on your surrounding people that come across in a unhappy way. If you choose to be a grouch then so be it, but if that's not what you want then you can give this a try.
This is just an easier way to look at and establish the bad mood setting situations. Once you have reached that state of recognition, then you can package it as a garbage truck and make what you want of it. Whether you choose to let it affect your mood is entirely up to you. But if you want to be a more happy-go-lucky kinda person then you can us the garbage truck outlook and dump that negative waste off to the side and move on. For example, a lot of people have issues and conflicts with driving on a regular basis, or just now and then. Well if you take that persons negativity that just swerved and cut you off and label it a trash truck and then dispose of it and not ride their ass or flash inappropriate hand gestures then it won't ruin your day. If you don't let things bother you then you wont have such a problem with passing that onto other people and therefor you have formed a more peaceful world. This doesn't mean you can't use helping tools in snuffing out the anger, such as calm music, it's just a way to label it. I hope you remember this theory and try if out sometime on something that used to anger your emotions.
