Whether it be to teach you a valuable lesson, help you become the best you that you can be or simply to test you.
Different people will teach you different things, but in every lesson you must always remember that life is too short to hold on to anger and spite. Take the lessons you learn in your past, and use them to help you better your future self.
Find it in your heart to give thanks to those people that perhaps caused you pain - they too taught you a lesson.
