"I'm not sure I could boil it down to one thing. Life isn’t usually that simple. But if I really, really had to boil it down to one thing, I would say this: responsiveness."So. True.
"So many people I meet are unresponsive. They don’t return their phone calls promptly. They don’t answer their emails quickly. They don’t complete their assignments on time. They promise to do something and never follow through. They have to be reminded, prodded, and nagged. This behavior creates work for everyone else and eats into their own productivity. Sadly, they seem oblivious to it."
(and I definitely have room for improvement here...)
