One of the things Dean has reemphasized for me is the need to not just "Think A Little Different", but to keep a good positive attitude and focus on the opportunities that exist around us.
Our minds can't distinguish between a real and an imagined experience. I love that Dean challenges us to REALLY step out of our comfort zone and create our success. Imagining that success and planning for it is an important first step.
The only thing holding us back is ourself. If we can break through the false illusions we put in front of ourselves, then nothing can keep us from success.
