No, the difficulty is not the lack of ideas. The difficulty is to develop a taste for which strategy is suitable for your personal circumstances and goals, and which ones look viable even before you devote the time to diligently backtest them. This taste for prospective strategies is what I will try to convey in this chapter.

First, we have a fire hydrant (hydrogen) with helium-filled balloons (helium) tied to the top of the hydrant. The helium balloons are touching the light bulb (lithium). The light bulb is burning the different berries (beryllium). The berries are being eaten by a smelly wild boar (boron). A car with a bun attached to it (carbon)

I passionately want you to believe in a specific counterfactual world—the one with systematic behavior change at the center of the creation process—and adopt it as your own.

we mean that Mark Manson doesn’t care about adversity in the face of his goals, he doesn’t care about pissing some people off to do what he feels is right or important or noble. We

Instead, we're moving into Software 2.0 (a shift that Michael Taylor recently wrote about), where we describe a goal that we want to achieve and train a model to accomplish it. Rather than having a human write instructions for the computer to follow, training works by searching through a space of possible programs until we find one that works. In

This is because you and I have different values than Mustaine does, and we measure ourselves by different metrics. Our metrics are probably more like “I don’t want to work a job for a boss I hate,” or “I’d like to earn enough money to send my kid to a good school,” or “I’d be happy to not wake up in a drainage ditch.” And by these metrics, Mustaine

The issue is that personality is extremely individual. Traits that play a critical role in peak performance—such as your risk tolerance or where you land on the introversion-to-extroversion scale—are genetically coded, neurobiologically hardwired, and difficult to change. Add in all the possible environmental influences that come from variations in

Sherlock Holmes has illustrated the four elements most likely to allow us to do just that: selectivity, objectivity, inclusivity, and engagement.

Pilots are tightly scoped interventions that we expect not to work (remember, we have to explicitly prove efficacy as a defense against confirmation bias), so we use small populations, focus on speed to market, and do them in an operationally dirty way. Besides being fun to say, “operationally dirty” just means that we’re shooting for minimal
