“You try to make plans for people, and the people make other plans.” – Terry Pratchett

“The planning fallacy occurs when individuals and groups try to plan complex projects and underestimate the true cost, expanse, and time of the project. Mario Weick and Ana Guinote found that people in a position of power are particularly vulnerable to the planning fallacy. Perhaps feeling powerful causes them to focus on getting what they want and to ignore hurdles, or having so much self-confidence causes them to avoid worst case scenarios.” – Michael A. Roberto, Transformational Leadership

“It is important that we know where we come from, because if you don’t know where you come from, then you don’t know where you are, and if you don’t know where you are, then you don’t know where you are going. And if you don’t know where you’re going, you’re probably going wrong.” – Terry Pratchett

“Always remember where you are going and never forget where you’ve been.” – today’s cookie fortune
