We have all heard that in order to change your life, you must change your habits. And that there are good habits and bad habits. But why are habits so important? This quote helps us understand not only why they’re so important, but how the developed over the course of millions of years.
Habits, scientists say, emerge because the brain is constantly looking for ways to save effort. Left to its own devices, the brain will try to make almost any routine into a habit, because habits allow our minds to ramp down more often. This effort-saving instinct is a huge advantage. An efficient brain requires less room, which makes for a smaller head, which makes childbirth easier and therefore causes fewer infant and mother deaths. An efficient brain also allows us to stop thinking constantly about basic behaviors, such as walking and choosing what to eat, so we can devote mental energy to inventing spears, irrigation systems, and, eventualy, airplanes and video games.” -Charles Duhigg (pg.17,18)
