In a way nature protects us by shielding us from knowledge of the difficulties and obstacles that lie ahead because if we really know all of the problems we would face, the setbacks, the sufferings, the temporary failure, and disappointments - many of us would hesitate about everything, even starting out. Quitting is a habit and if you quit the first time you run into difficulties, you’ll always quit when the going gets rough, and in effect, you’ll establish a pattern for failure rather than a pattern for success.
Decision fatigue is a psychological phenomenon surrounding a person’s ability or capacity to make decisions. In other words, the more decisions you have to make, the more fatigue you develop and the more difficult it can become. This fatigue applies to all decisions, not simply the large or more difficult ones as when there are too many options, we tend to feel overwhelmed, anxious, stressed or otherwise out of sorts.
