the trap of marginal thinking

By May 10, 2012Leadership

“If you give in to “just this once,” based on a marginal-cost analysis, you’ll regret where you end up. That’s the lesson I learned: it’s easier to hold to your principles 100 percent of the time than it is to hold to them 98 percent of the time. The boundary—your personal moral line—is powerful because you don’t cross it; if you have justified doing it once, there’s nothing to stop you doing it again.”

— Clayton Christensen, Harvard Business School
