Hmm. I've never actually thought of what sort of moral code I had, and I never really lived by any principles in particular, but...
I'll come up with a few principles, not ordered in any matter of importance in particular.
"Be mindful of things as they are, not judge them as they seem." - The principle of passive awareness. Take a moment to see things from not just your own perspective, not just any particular side or party involved, but instead piece things together and take a gander at the big picture. This eventually involves finding ways to understand each individual's perspectives and ideas, taking them into account, and negotiating between them all to find a conclusion better for all parties involved in the long-term. Actively looking for something you agree with won't always wind up very well. For instance, take into account the stories of the people made out to be antagonists, and see their reasoning.
"Whatever it is you find yourself in, make sure you get through it." - The principle of endurance and self-sufficience. It's a given that things won't go well for you as often as you'd like. Misfortune is bound to happen. Prepare for it, be ready to withstand it, knowing what you need to know and cutting through the desire for sympathy and instead looking towards perservering through the tough shit without relying on others to validate your efforts. Not to say that you should go it alone, but when you dont have anyone, be ready for it, and be self-sufficient. Get through it.
"Strive for practicality. Move in straight lines, and get to the point." - The principle of efficiency and forthrightness. Prioritize the things that concern your necessities. The decorative shit comes later, just make sure to conserve your resources. Efficiency over comfort, if possible. When it comes down to it, you'll need to be blunt and make a statement on things as they are. Tell them exactly how it is. Soften them up if you find it necessary, but it comes as a secondary task. Look for ways to cut down time and save what you can get, you only have so much time to live.
That should sum up the basics of what I work with.
