A warrior is always aware of what is worth fighting for. He does not go into combat over things that do not concern him, and he never wastes his time over provocations.
Paulo CoelhoAll life's battles teach us something, even those we lose. When you grow up, you'll discover that you have defended lies, deceived yourself, or suffered foolishness. If you're a good warrior you will not blame yourself for this, but neither will you allow your mistakes to repeat themselves.
Paulo Coelho
