There's a great manifesto for change over at Change This, called "Manifesto to Accelerate: 15 Truths."
In it, author Dan Coughlin offers 15 Truths about accelerating momentum in business, and advises:
"To achieve sustained greatness in any business endeavor, you have to play at it with a Sustained And Focused Effort (SAFE)."
BOTTOMLINE: According to Coughlin, "The only way to sustain your focus and your effort through this challenge is to have fun while you do it. Enjoy the journey. Play it SAFE. Make it a game, not a job. Finally, find what you’re passionate about and pour it into what you do everyday in order to accelerate."
