Modern science texts tell high school students that they must first formulate a hypothesis and then conduct experiments to determine whether or not that hypothesis is true.

But that’s the opposite of what Charles Darwin did. He didn’t start out with a developed idea for the theory of natural selection. When he set out aboard the S.S. Beagle and traveled to the Galapagos Islands, he had no hypothesis.

Instead, Darwin set out to observe and collect notes and ideas.

The accumulation of these observations, learnings, ideas, and notes led to the formulation of a hypothesis and the subsequent development of the theory. He worked from the ground up, not from a hypothesis backward, like the “slip box” note-taking approach explained by Sönke Ahrens in How to Take Smart Notes.*

Cal Newport’s advice in So Good They Can’t Ignore You seems similar in this regard. Common career advice is to find something you’re “passionate” about and find a way to make that passion fit a job or career. But he argues the opposite—passion comes after someone develops experience in a job, skill, or career path. It’s not the catalyst (at least not in most cases).

One could argue that the “Slip Box” approach taken by researchers and scientists—gathering lots of ideas first, then developing an argument—would similarly benefit career planning.

Don’t start with a predetermined passion or career path. Instead, begin with exploration, discovery, and experimentation.

The result will be a fully fleshed-out and rewarding career with passion as the byproduct.

*Ahrens’s book is one of my favorites and directly responsible for my ability to write as much as I do.

The premise is simple to understand: collect ideas and write notes to yourself about your thoughts when reading, studying, or observing without worrying about “what it’s for. Over time, you’ll have collected so many ideas and come up with so many original ideas that different arguments and hypotheses will form almost of their own accord.
