Think in Probabilities, Not Certainties

Most of life is not black or white — it is shades of grey measured in percentages. Saying "I am 70% sure this will work" is not a sign of weakness; it is a sign of honesty. Probabilistic thinking means assigning rough likelihoods to outcomes instead of pretending you know for sure.

This changes how you make decisions. Instead of agonizing over which choice is "right," you pick the one with the best expected value across probable outcomes. And when things do not go your way, you can ask "Was the process sound?" rather than "Who screwed up?" A good bet can still lose. That does not make it a bad bet.
