Every day is a battle between willpower and temptation. Willpower constantly defends us against the lures of temptation. And yet willpower often fails us; temptations surround us, chipping away at our willpower. Willpower, overwhelmed, slowly weakens; eventually, it breaks down. Some of us may feel as if we are perpetually stuck on the losing side of this greater war between temptation and willpower.
We need a strategy, a way to fight back. The philosopher Sun Tzu's advice for those engaged in war was this: "The supreme art of war is to subdue the enemy without fighting." How can we defeat the enemy — temptation — without fighting? Fortunately, Fumio Sasaki offers a solution in his latest book, Hello Habits: A Minimalist's Guide to a Better Life.
Mr. Sasaki starts of by showing us how capricious willpower can be. Studies found that different factors could cause a lapse in a person's willpower — eating raw radishes while cookies lay tantalizingly on a table, decreasing serotonin levels (which simulates uncertainty), or thinking of something sad. But all this begs the question, "How is it that some people develop strong willpower?" Before we answer that, let us see why willpower is required at all in the first place.
There is this interesting phenomenon called hyperbolic discounting. In this phenomenon, people hyperbolize the worth of immediate rewards while overlooking the worth of future rewards. For example, in a study conducted by economist Richard Thaler, subjects were given the option of getting one apple a year in the future or two apples a year and one day into the future. Logically, most chose the option of getting two apples. However, when the experiment was modified to allow subjects to choose between getting one apple that day or two apples the next day, more subjects chose to receive one apple the same day. Hyperbolic discounting is an illustration of how irrational we can be.
Mr. Sasaki compares our decision-making process to the act of flipping a coin. The results of our decisions are unpredictable due to our flawed logic. The more we flip the coin, we increase the probability that we will make the wrong decision.
The solution then is to not flip the coin at all: to subdue temptation without fighting. We can do this by suppressing our awareness. When we can do something without using our awareness, it no longer requires us to go through our flawed decision-making process. So by programming into our minds certain actions we can automatically do without our awareness, we can subdue temptation. These actions are what we call habits.
This book is overflowing with practical advice for creating new and better habits. Make it as easy as possible to practice good habits while making it as hard as possible to practice the bad ones, Mr. Sasaki suggests. When breaking a bad habit, quit completely or else you'll always find a way to make an exception. Making your goals as easy as possible — doing one push up, running for one kilometer, or reading for just five minutes — will make it easier for you to maintain them; you can then build from there.
The book — like our willpower — loses its vigor towards the end. Similar to Mr. Sasaki's last book (about minimalism), the ending is more of a philosophical discussion of the general life lessons we can draw from the book. In his first book, Mr. Sasaki more or less stuck to the concept of minimalism by teaching us how it could become a philosophy for living life. However, in this book, Mr. Sasaki begins to talk about what we can learn about the concepts of effort and talent, and starts to wander away from the subject of habits. While the discussion was interesting, it would have been more suitable as its own book.
However, the practical advice and words of wisdom sprinkled throughout its pages make Hello Habits worth the read. And now that I've finished this review, I'm going to start writing another one to develop my habit of writing every day.
