Anything that can go wrong will go wrong.” https://en.wikipedia.org/wiki/Murphy%27s_law
What is Murphy’s law?
Murphy’s law is a popular adage that says if something has a chance of going wrong, it eventually will. It is often used as a reminder to expect mistakes, delays, and unexpected failures, especially in complex plans or systems.
The practical lesson is not pessimism, but preparation: design plans with backups, check assumptions, and leave room for things to fail.
