I saw this quote on the CodeBlack Life Facebook page "There are so many people out there who will tell you that you can't. What you've got to do is turn around and say 'Watch me.'"
No dream is too big
We will always have doubts, and we will always have people in our lives who are scared that we will fail, or even want us to fail, but we need to remember that only we can follow our dreams, and only we are responsible if it doesn't happen.
If your dream seems too big for others around you, don't stop chasing it. Just stop listening to those trying to hold you back. When your inner voice fills you with fear of failure, turn in defiance and say loudly "Watch me!". Remember that self doubt killed more dreams than failure ever did.
