Rick Perry

I believe we have become paralyzed, paralyzed by our desire to be loved. Now our founding fathers had the wisdom to know that social acceptance and popularity were fleeing, and that this country's principles needed to be rooted in strengths greater than the passions and the emotions of the times.

I would absolutely recommend against excessive positivity and optimism. Any positive emotion that you're infusing into a workplace needs to be grounded in reality. If it's not realistic, sincere, meaningful, and individualized, it won't do much good.
