Knowing how things work makes you calmer when they break. Understanding is a kind of peace.

Panic mostly comes from not knowing what a failure means. A noise from the engine is terrifying if it could be anything and manageable if you know it is the belt. Understanding shrinks the range of possibilities, and a smaller range is easier to stand in. That is why people who know a system stay steady in front of it while everyone else assumes the worst.

Learn the basic workings of one thing you depend on and do not understand. Your bike, your bank account, the heating, the software you use daily. An hour now buys a much quieter version of the day it goes wrong.
