The gulf between the information we proclaim & the information we know to be true is vast. In other words: we say one thing & do another.
Steven LevittMany of life's decisions are hard. What kind of career should you pursue? Does your ailing mother need to be put in a nursing home? You and your spouse already have two kids; should you have a third?such decisions are hard for a number of reasons. For one the stakes are high. There's also a great deal of uncertainty involved. Above all, decisions like these are rare, which means you don't get much practice making them. You've probably gotten good at buying groceries, since you do it so often, but buying your first house is another thing entirely.
Steven LevittSolving a problem is hard enough; it gets that much harder if youโve decided beforehand it canโt be done.
