V01f my dear fellow the right attitude to have is one of timid optimism, like "Perhaps today there will be no problem?"

Are you familiar with Marcus Aurelius, the roman emperor and author? No?
He adhered to stoicism, a philosophy I warmly recommend. For instance observe how he handled annoying people. (You think that if you are a Roman Caesar you don't have to meet annoying people but obviously you have to..) Every morning Marcus said to himself, "Today I know that I will meet at least one unreasonable person". Then the day roll along and then, lo and behold comes the unreasonable person. Do Marcus got angry? No no, he just said to himself. "I was right again!".
