Diminishing returns means that the more you experience something, the less rewarding it becomes. The classic example is money. The difference between earning $20,000 and $40,000 is huge and life-changing. The difference between earning $120,000 and $140,000 means your car has slightly nicer seat heaters. The difference between earning $127,020,000 and $127,040,000 is basically a rounding error on your tax return.4
The concept of diminishing returns applies to most experiences that are complex and novel, and even many of the mundane ones. The number of showers you take in a day, the number of chicken wings you inhale during happy hour, the number of trips home to visit your mother in a year—these are all experiences that start out highly valuable at first but then diminish in value the more frequently you do them (sorry, Mom).
Another example: studies on work productivity show that we’re really only productive for the first four to five hours of each day.5 Everything after that suffers severely diminished returns, to the point where the difference between working for 12 hours and 16 hours is basically nothing (not counting sleep deprivation).6
Friendships operate on a diminishing returns curve. Having one friend is vital. Having two is clearly better than one. But having 10 instead of 9 changes little in your life. And having 21 instead of 20 just makes remembering people’s names that much more difficult.
Sex has diminishing returns, as does eating, sleeping, drinking alcohol, working out at the gym, reading books, taking vacations, hiring employees, consuming caffeine, saving for retirement, scheduling business meetings, studying for an exam, masturbating, staying up late to play video games—the examples are endless. All give back less the more you do them, the more you try, or the more you have. All operate on a diminishing returns curve.
But there’s another curve, one that you’ve probably never seen or heard of before—and that’s largely because I make a lot of this shit up. That’s the inverted curve:7
The inverted curve is the bizarro “Twilight Zone” curve, where effort and reward have a negative correlation—that is, the more effort you put into doing something, the more you will fail to do it.
Drown-proofing exists on an inverted curve. The more effort you put into rising to the surface, the more likely you will be to fail at it. Similarly, the more you want to breathe, the more likely you are to choke on a bunch of chlorinated piss water.
But I know you’re thinking, “So what, Mark? I’ve usually had too many piña coladas to even find the deep end of the pool, much less bind my arms and legs and try to survive in it. Who gives a shit about inverted curves?”
It’s true, few things in life function on an inverted curve. But the few things that do are extremely important. In fact, I will argue that the most important experiences and goals in life all exist on an inverted curve.
