You are young, healthy, English speaking, male, from a comfortable family background and living in a wealthy country.
Other than your being in the most likely to be mugged category you doubtless have one of the easiest lives in the world. Now without a frame of reference you are unlikely to be able to do much with that knowledge seen as you have not ever been otherwise and your only basis for a comparison is to those in a similar position. It is important though so it is mentioned.
My personal method for this involves dismissing all other humans as toys and the realisation that the only things I care about are continuing to live and learning some more stuff. I am in the same position as you (young, health, English speaking....) and as such it is pretty hard for me to die/not continue living quite happily. It was not hard to learn enough to ensure that I was always able to get more to learn either.
Couple that with a basic understanding of probability and mathematics and it gets even better. Lesson one there is a George Carlin quote - "Think of how stupid the average person is, and realize half of them are stupider than that.".
What then is left to cause you aggro?
