The passion you have will be a double-edged sword. It will energize you and empower you to stretch, and to go that extra distance to create and achieve. Unfortunately, it will also lay you open and expose you to those who would ridicule and destroy rather than inspire and challenge. You cannot have one without the other. You must choose. Are you going to be a photocopy drone of a thousand others and mindlessly turn out formula products that everyone has seen and heard over and over again? Or are you going to stretch and do something new and different? Therein lies the challenge; therein lies the passion.
