Confirming your own brilliance is about you giving yourself permission to believe in yourself. I love this quote by the late Muhammad Ali, "I am the greatest. I said that even before I knew I was." Like Ali, we have to start telling ourselves that "I am the greatest," even when it doesn't look like it. Ali started telling himself he was the greatest long before it looked like it on the outside or before others agreed.
Oftentimes we don't think that we are the greatest, special, or amazing. We look at our failures, our mistakes, our shortcomings and believe those things define who we really are. But we are more than our failures, mistakes, and our missteps. By confirming your brilliance, it helps to remove the focus of past failures and mistakes. We have to confirm that our brilliance is still there...despite what it may have looked like in the past or even today.
My challenge for you is to confirm your brilliance, validate yourself as the greatest...even if it doesn't look like it today. I challenge you to tell yourself "I am the greatest" in the midst of so many voices telling you that you are not.
