Knowing who you are is really important in this life. Define it for yourself do not give anyone a chance to define it for you because it's not their life. Knowing who you are can help you stay focused on your goals and vision. No one can enter your mind if you know who you are and that means you cannot be broken by others and what they say because it will just be words that do not mean anything to you. Remind yourself every day of the person you are and never forget it.
