CPU

Your brain is the most advanced “CPU” we know, and understanding how it works is the first step to using it better in daily life and at work.

In terms of the brain, you can, in a crude way, think of the human brain as a computer.

–Paul Greengard, American neuroscientist

Thanks to movies like 2001: A Space Odyssey, The Matrix, or I, Robot, many of us imagine a processor as something similar to a human brain. In reality, if you compare them, a modern processor is closer to an abacus than to the brain of a chicken. We did not design processors to be “the brain” of a system; we designed them as extremely fast calculators that can perform huge amounts of simple operations in a very short time.

The fact that fast hardware plus clever software can simulate human behaviour is impressive. But the key word is “simulate”. We do not have a set of written instructions in our heads like the software that runs in computers. Instead, we have synapses and a biological architecture shaped over millions of years, which works in a very different way. Throughout this book, you will find several analogies between computers and our bodies. Their goal is to make ideas easier to visualise, not to say that we are machines. The key message of this section is that we do not have a processor in our brain—and we do not need one. We have something better: the most sophisticated problem‑solving “system” we currently know.

When Alan Turing designed the first general‑purpose problem‑solving machine, he focused on what machines do well: repeating simple steps much faster and more reliably than any person. The goal of Soft Skills is to focus on what humans do well: understanding context, making decisions, learning, and working with other people.

In the following chapters of this part, we will look at the elements of our thinking that behave as if they were parts of a processor, and how we can make them work more efficiently in our everyday life.

Task manager

We all have a kind of internal “task manager”. A processor executes one instruction after another; in a similar way, we move through our daily tasks, one after another, often switching between them. How we choose, sort, and drop these tasks has a direct impact on the results we deliver and on our stress level.

In this chapter, we will see how to structure and manage tasks so we maximise impact with reasonable effort. It is not only about doing more; it is about doing what really matters and investing our time and energy where they create the most value.

RAM

We also rely on something similar to “RAM”: our short‑term or working memory. Like RAM, it is temporary and limited, but very powerful when we use it for the right things. We are very good at making connections and generating new ideas, but we are not so good at reliably storing and recalling small, isolated pieces of information.

In this part, we will see how to use this instant memory for its real purpose: holding information just long enough to do something with it—understand it, transform it, or move it to a better place. This leads to a more efficient use of our mental “storage”, less wasted effort, and less “mental energy” needed to perform at our best.

Process organization

One of the hardest parts of our daily work is deciding where to start. We constantly ask ourselves: What should I do first? What is most important? What can I delegate? What can I ignore? These questions come up when we plan our day, our week, or even our year.

By preparing and filtering our workload in advance, we can focus on what is truly necessary and get more from the same amount of effort. Defining simple procedures and executing tasks in an efficient order increases our capacity and frees up time and attention for the problems that really deserve them.

Loading new content

We can also add new “apps” to our system: new skills, tools, and ways of thinking. Learning is something we are born with, but as time passes, it can feel harder to add new abilities. We do not have a Matrix‑style port in the back of our head, but we do have our own “App Store”: books, courses, colleagues, and experiences.

In this section, we will explore how to make learning new skills easier and more intentional. A crucial part of that is choosing what to learn and what to ignore. Not every topic is equally important at every stage of life, and not every skill needs the same level of mastery to be useful in your work.
