Page 74 rule number six, post a sign that says no energy vampires allowed on your bus.
— from Fuel (Energy)
In the book
The rule that follows is to fuel your ride with positive energy, because enthusiasm is contagious — it tends to draw good people toward you and to energize the ones already in your formation. And the discipline that follows that is to guard the tank fiercely: allow no energy vampires aboard, the people who drain you and leave you wondering when they will finally leave; surround yourself instead with the people who fill you, not those who empty you. Complaining, by the way, is simply negative energy leaving your own mouth — pour out enough of it and you become an energy vampire to everyone around you. — Fuel (Energy)
