    Amazon sells 1,161 kinds of toilet brushes. I know this because I recently spent an evening trying to choose one of them for the bathroom in my new apartment. Nearly an hour later, after having read countless contradictory (矛盾的) reviews and considering far too many choices, I felt tired and simply gave up. The next day, I happily bought the only toilet brush the local dollar store offered.

Too many choices exhaust us, make us unhappy and lead us to sometimes flee from making a decision altogether. Researcher Barry Schwartz calls this “choice overload”. And it’s not just insignificant details like which brush to wipe the inside of the toilet with — having too many choices in our creative and professional lives can lead us to avoid making important decisions.

Understanding how and why we make decisions can perhaps help us make better choices down the line. We make poorer decisions when we are tired. It’s caused by decision fatigue (疲劳). The mind can only sort through so many choices and make so many choices before it starts to run out of steam. That’s why impulse buys like candy bars and magazines at the checkout aisle in the grocery store can be hard to resist. We’ve exhausted all our good decision-making skills.

The same goes for our workday. Making lots of decisions not only exhausts us; it can put us in a bad mood. That’s why it’s necessary to make your most important decisions in the morning rather than at the end of an exhausting day when your energy has been used up. The idiom “sleep on it” is indeed effective when it comes to making big decisions.

When we’re tired, we tend to conserve our energy by making choices based on a single factor like price, rather than considering all the other determinants that go into making the best decision. When you’re doing this, you are acting as what researchers call a cognitive miser (小气鬼).

To conclude, letting yourself have fewer choices to choose from can help you arrive at a more creative answer.
