The 5 Most Famous Laws in The World

1. Dunning-Kruger Law:
Stupid people think they're smart. Smart people doubt themselves. The less you know, the more confident you are.

2. Parkinson's Law:
Work expands to fill the time available, so longer deadlines often lead to slower completion.

3. Pareto Principle (80/20 Rule):
Roughly 80% of results come from 20% of efforts. Focus on the few things that actually matter.

4. Hanlon's Razor:
People aren't trying to hurt you, they're just being careless. That person who didn't text back? They forgot, not ignoring you.

5. Peter's Law:
Good workers become bad managers. Being great at your job doesn't mean you'll be great at the next level.

And I would add

6. Murphy's Law:
Anything that can go wrong, will, when you least expect and can't afford.

@MorpheusB Brandolini’s Law, a.k.a. “The Asymmetry of Bullshit”

The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.

@JustinDerrick never knew this one, but you correct!
