What's an 'A' Worth?

Parents should appreciate the effort and the love of learning and not only  the results. Paying your children for an 'A' doesn´t necessary motivate them to study more and  focus on short term results, rather than long term goals. I like this article that appears today  in The Wall Street Journal: "Many parents pay their kids for top grades. Even when it works, it may not be the smartest investment".
