You have to be confident enough and tough enough to follow your dreams.
Do you know why?
Your dreams are your dreams and belong to no one else! The hardest part about having dreams is being strong and courageous enough to follow through and make them true. You will encounter many people who will try to deter you from your dream. They may even want you to help them reach their dreams and forgo your own!
You must be confident about what you want for yourself and your life!
