No greater teacher than experience. Can't love another until you've learned to love yourself. Can't appreciate God unless you've been a little devil. I will live well because I know so good how living bad feels. I will think positively because I've tried to be negative and it hurt. I will forgive because animosity was a poison that killed me from inside out. What I have done has taught me what I should do.
My father use to say " the best lesson in the world is a brought lesson". When we feel the fire and its affects with our own skin, the conclusion is permanently rooted in our minds for recall, if we ever consider repeat exposure to the same pain; only a fool seeks to duplicate negative and damaging experience.
