[ad_1] “Success can get you to the top of a beautiful cliff, but then propel you right over the edge of it.” As a Mustachian, there’s a good chance that you are a bit of an overachiever. Maybe you fought hard to get exceptional grades in school, or perhaps you have always dominated in your career or your Ultramarathon habit or your hobbies – or maybe all of the above. In the big picture, this usually leads to having a “successful” life, because of this basic math: Traditional Success = How much work you do x How much society happens to value your work The Nitty Gritty of Traditional Success Now, lest the Internet Privilege Police head straight to Twitter to start writing out citations, Traditional Success is not a measure of your worthiness as a human being. We’re just talking about the old-fashioned, Smiling 1950s Man definition of success. And since we’re all scientists here, we could break the “Work” side of it down a bit further: And thus, you could say that on average, doing more stuff produces more traditional success. But then what? This is the point where a lot of smart, driven, born-lucky people drive themselves up the Winding Road of Challenge and then right off the edge of the Cliff of Success. If you’re still on the way up, or stuck at the bottom, it is difficult to even imagine the idea of “too much success”. But it’s a real thing, and it happens much more quickly than the modern overachiever would like to admit. Observe the following cautionary tale: Diana is the director of engineering in a Silicon Valley tech startup. The work is intense, but they are almost over the hump – the company went public last month, and she owns shares that are worth over $10 million at today’s share price. They will vest over the next five years, so she just needs to grind this out and then she will be set for life. Sounds great, right? Except this is Diana’s third smashing success. She was already set for life after the second company was acquired, and even before that, her first decade as a rising star at a large company had already left her with over $2 million of investments and a paid-off house in hella expensive Cupertino, California. She had more than enough to retire, twenty years ago! To many people who are less fortunate, the present situation would still sound like great fortune, and in some ways, it is. Becoming a Director of Engineering is (usually) far better than a punch in the face. But Diana is now 52 years old, with a collection of increasingly severe back and neck problems and a few medical prescriptions piling up. She has two grown children in their twenties, but wishes she had been able to spend more time with them as they grew up. She has all the money in the world, but still almost no free time, and this next five years is starting to look like an eternity. What happened here? Diana is in good company, because many of our hardest-working people fall into this same trap. They have the talent and the great work habits figured out, but they are still missing one last concept – the idea of the sweet spot. Fig. 1: What is the ideal length of a high-end career? Diana could have stopped after the first company, or the second, but her career success took on a momentum of its own, so she kept doubling down without stopping to consider why she was doing it – and what she was giving up in exchange. Once you learn to see the phenomenon of the sweet spot, you will start noticing it everywhere. And it is an amazingly useful thing to start watching and fine-tuning to get the most out of your own life. Fig.2: What is the ideal amount of Anything? The Sweet Spot of Physical Training When a non-runner starts running, they will see immediate benefits. In the process of going from being unable to jog across a parking lot, to being able to easily jog a brisk mile, your entire body will transform for the better. Muscles and bones get stronger, heart and lungs expand and reach out to give your body a healthy embrace, brain functioning and mood and hormones smooth out and normalize. Training your way up to become a two mile runner still brings great benefits – just slightly smaller. The fifth through twentieth mile turn you into a hyper efficient machine, but some people start seeing joint injuries as they rise through the ranks. And by the time you reach the fringe world of 100-mile runners, serious injuries and surgeries are completely normal – as well as unexpected organ failures in otherwise young, healthy people. The sweet spot for daily running for maximum health is somewhere the middle. All around us, seemingly unrelated things follow this same pattern, from career work to physical exertion to parenting strategy. Fame and Fortune – be careful what you wish for Fame definitely has a sweet spot. Building up a good reputation in your community can open the door to better friendships, jobs, relationships, and more fun in general. But as that reputation expands outwards to become fame, you get the “reward” of constant coverage in gossip magazines and waking up to find photographers and news reporters on your front lawn. At the extreme end, you need to mobilize a team of armored vehicles and line your route with snipers every time you leave your well-guarded compound. Even money, our humble and ever-willing servant is subject to this phenomenon. It certainly helps us meet our basic needs, but there is a certain point at which Mo Money can become Mo Problems. The first bit of monetary surplus can be fun as you can afford a nice house and good food. Then the next chunk seems fun but also causes distractions as
