I have a few:

"Never go back on your word": I make a promise, or say I will do something, and I do it. I heard one time that a man has no greater honor than his word, and thought that was a pretty good code to live by. This was also influenced by Naruto somewhat.

I also have a moral code which I TRY to live by, yet rarely succeed. That is simply to put others ahead of myself, but to disregard the wants of others if there is some higher priority. So in order of importance, I try to tend to: 1. What needs to be done. 2. The needs/wants of others. And then, 3. The needs/wants of myself.

"Make them proud': This is just to remind me of how much I have in my life, and that none of it should be wasted. I always feel I owe a lot to the people who have made sacrifices for me (not just my parents, either). So this is kind of a motivational motto. It's similar to one I used to have that went "to whom much is given, much is expected" but that one seemed too rigid and put too much pressure on me, so I settled for one that acknowledged those who support me.

"Live a life without regrets": Simple enough. I'm usually pretty shy person, and I'm not inclined to take chances. This is just to remind me that it's no good sitting around, thinking of what could have been.

"Meh, that's life": Similar to "shit happens"

"Never take raisins from a rabbit": From Baulder's Gate. This one gets a special mention [img]i/expressions/face-icon-small-tongue.gif[/img]
