" No is easier to do, yes is easier to say. No is no to one thing. Yes is no to a thousand things. No is a precision instrument, a surgeon’s scalpel, a laser beam focused on one point. Yes is a blunt object, a club, a fisherman’s net that catches everything indiscriminately. No is specific. Yes is general. "

― Jason Fried , It Doesn't Have to Be Crazy at Work
