Why Multitasking Makes You Slower (and What to Do Instead)
Every day we compete with too many things for our attention: messages, meetings, ideas that pop up out of nowhere, urgent requests while we’re already busy with something else. If we want to do work that matters, we need a simple way to decide what to do, what to postpone, and what to ignore.
We often say we’re “multitasking,” but that’s not really what’s happening. Most of the time we’re simply moving our attention very quickly from one task to another. It feels efficient, but in practice it usually slows us down.
The reason is simple: every time we switch tasks we pay a mental cost. We need a few moments to remember where we were, what we were thinking, and what comes next. That cost may seem small, but repeated many times a day it becomes expensive.
A simple example makes this clear: try stirring your coffee while reading a paragraph carefully. At some point, one of the two actions slows down or stops, because your attention has shifted to the other.
The key idea: the goal isn’t to turn yourself into a machine that does more and more. The goal is to reduce friction, make better decisions, and spend your energy on the work that actually matters.
This is just the starting point of the Task Manager chapter, the first piece of the CPU layer in The Engineering Protocol Stack. If you want the full development — including how to prioritize for real instead of just “doing more” — the book is available on Leanpub.
