Entropy Doesn't Care About Your Plans

The second law of thermodynamics says disorder always increases. A hot coffee cools. A sandcastle crumbles. Order never maintains itself for free.

Here's the unsettling part: life itself is a temporary rebellion against entropy. You stay organized only by constantly burning energy — eating, sleeping, repairing.

The moment you stop putting energy in, things fall apart. Your body. Your skills. Your relationships. Your room.

Nothing decays because you did something wrong. It decays because that's the default. Staying sharp is the exception you pay for daily.
