Rem Koolhaas

You couldn't get me to go travel around and sit in a hotel room again. I have no interest in doing that. So everybody's happy. I am, at 74. Some people like doing it, but I never was much for that, anyway. It's a lot of work. So the only thing I miss about all of it is the camaraderie of the tour, but that doesn't offset the rest of it.

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.

Sometimes it's even hard to tell the difference between a tic and a compulsion. But while tics stem from an urge in a specific part of the body - either completely unconsciously or through a premonitory sensation that's satisfied only by the tic - OCD bubbles up as conscious thoughts in the mind.
