Rabies vaccine developer, 🧫 Father of Microbiology Louis Pasteur from France 🇫🇷:

For those with vested interests, you must demonstrate your strength and intelligence,

For those without vested interests, showing your politeness is enough.

Those who are overly calculative are only suitable for buying groceries, not for doing great things.

The lower classes, if you flatter them, they will bully you; if you bully them, they will flatter you.
