Min-maxing in life

When min-maxing in games, you choose to minimize the least effective traits/skills of your character so you can instead maximize the most effective ones. The idea is that it's better to have a character that is exceptional in a main trait/skill than one that's just okay in everything.

Applying this IRL (in real life) means choosing to be deficient in most areas so you can excel in a few. It's similar to The 80/20 Principle, and Discipline means saying no.
