These people understand that evidence isn't, and never will be, the key. Self belief is their master. This type of belief is unflappable, living deep in their core. It looks at past failure as something that doesn't exist, created by those who were too weak to look for an alternative. This 'F' word is a good word, only fueling their intense passion to succeed when others say it will be impossible... knocking down walls built by the scared.
In their world, evidence is all around, especially living in their minds and imaginations. They don't need a past to tell them, "yes, you are worthy." Their main objective is to create a present that proves the past is unimportant, and the future awaits with open arms. Of course, the past should be learned from, potentially improving the present, but never playing a role in whether or not we reach the finish line today.
"I have not failed. I've just found 10,000 ways that won't work."
Thomas A. Edison
You see... these few, special players in our never ending game have learned that possibility begins, not with the opinions of others or actions from our past-selves, but rather from our thoughts and beliefs. They believe because they've chosen to believe, not because someone has told them it was safe and probable. They believe because they know negative past actions don't dictate positive future results!
Evidence: Need any?
