I'm not sure if most people have a personal philosophy. It's not something you wear on your sleeve, so I might be wrong. Maybe the only way to get to someone's personal philosophy is to get into an argument with them. They say one can learn a lot about a person through combat.
Well I spent a lot of time on mine, and I'm rightfully proud of it.
The origins of mine came about when, late at night, I was lying in bed, staring at the ceiling, my whole world crumbling to pieces, for my ex girlfriend had left me. There had to be a rational explanation for this. There had to be some way to accept this. There had to be a train of thought that would explain the world, and thus, allow me to accept its ways completely.
Looking back, I had blindly accepted many false ideals from society. These ideals never fit when applied to the world. Nietzsche was not the only one, but he argued that idealism only results in disappointment, and thus was the real enemy of mankind. Applying all your energy to achieve an ideal will not let you achieve the ideal - but turning your back on the ideal is not viable either. What then, should one do?
Society is full of contradictions. Beauty? Society dictates that we should think of it as "ah, it's only the surface", yet we all know it is not true. Women are disillusioned of this false ideal early in life. Money, power and popularity are all things that society tells us are "hollow", and "not worth striving for". We should be in love, yet conceal the fact that we are in love. And whenever the word pride or "big ego" comes up, the first question someone invariably has is how not to have the two aforementioned qualities.
Resolving these contradictions and answering these questions kept me awake for entire nights. Eventually, I came up with the following maxim:
I shall trust nothing but my own judgment.
