If everyone were given a dollar for the times they were told they were incapable of something; all of us would be millionaires. Never look to anyone else for validation, inspiration, or motivation. If you happen to see it in another, so be it. But never search for these things. Only you have everything you need, and life is a long journey to discover everything about yourself. Do not get to the end of your life and realize you are still a mystery. Whatever you are currently doing, commit everything to it. Decide that you would rather die than give up on anything. You will fail, you will feel pain, you will question yourself, but you will never quit. You are literally willing to do everything necessary to find out who you are.
