Don't change yourself so that others will like you. It's their loss. Be with those who care.
No matter how educated or rich you are, how you treat people, tells all.
Sorry means nothing without changing. Actions speak louder than words.
Never regret being a good person to the wrong people. Your behavior says everything about you, and their behavior says enough about them.
The best thing about the worst time of your life is that you get to see the true colors of everyone.
