Surreal as it seems, being a pessimist can teach you many things.
One of those things is to always be prepared. And you’re not even going to make an effort for that, it will all come naturally.

It will come as a natural defense and you can bet it’s going to save your back from a lot of nasty situations you’re going to find yourself in.
