The philosopher George Santayana famously wrote: “Those who cannot remember the past are condemned to repeat it.” It’s hardly the most cheerful of lines. But what if we look at it a little differently? Suppose we were to modify things a bit: “Those who cannot remember how they came by their success will find it hard to be successful in the future.” Not a quote that is destined to become a classic, perhaps, but it allows me to illustrate an important point.
