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: You're not busy. You're just bad at managing time. A task expands to fill whatever deadline you set. 3. Pareto Law (80/20 Rule): 20% of your effort gives you 80% of your results. 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.
