Never afford someone the ability that, within a day, they can completely ruin your entire life plan. Because, someday, they will. Even if they don't want to, life will find a way to force them to, just to spite you. Never rely on someone, assign the meaning in your life to them, because life will take them from you, and you'll find yourself drowning in the waters of this world's uncaring, meaningless existence. You have to give it meaning, and a solid, unchanging meaning at that, otherwise you'll end up like me. Lost. Drowning. Slowly dying. Maybe even just as cold and uncaring as the world that's drowning you.
