Recently, I was reading a great article at The 99 Percent entitled The 40-30-30 Rule: Why Risk Is Worth It . I originally intended to include it in my weekly roundup, but as I thought about the 40-30-30 idea, I found that the connections to careers, personal finance, and life were profound. What is the 40-30-30 rule? Simply put, it’s an argument that when you prepare for anything in life, only 40% of the preparation is physical – the rest is mental. Thirty percent of preparation is technical skill and experience, and the second thirty percent is the willingness to take risks. This “rule” comes up again and again in all different areas of life. Here are several examples from my own life where I’ve seen it. When I’m playing a game I’ve played a lot of times before, I have an intuition as to what move to make next, built from years and years of experience (the 30% that comes from technical skill and experience). However, I also find that it’s very easy to just keep using the same strategy over and over again because I’ve somehow come to the conclusion that it’s the best one. So, if I combine that technical skill and experience with a risky new strategy I’ve devised (the other 30%), I might lose – but I might also devise a way of playing that’s even better.
