The second law of thermodynamics, which relies on a concept known as entropy. Entropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work.

A lot of things in the world depend on our ability to work against disorder, the default state of the world and things in it is chaos, eventually, everything will lose its hotness and bend towards coldness and decay.

The only time you can do anything meaningful is when you become orderly. Put a lot of intentional energy into planning; planning depends on your ability to have clarity of mind to be organized.
