Your life is important and your purpose is your own. Know "that" if you know nothing else. You don't have to explain yourself to anyone else or make excuses if you don't want to. It's your existence, use it wisely.

Know that you are not alone in whatever you are feeling. There is understanding and honesty in everything you experience. The world has a place for you and you should not feel bad or less than someone else if you do not know what your purpose is because you have your entire life to figure it out and it's okay to move around in your life and change your mind. It's okay to step off your current path onto another one if you want to.
