What a man sees depends both upon what he looks at and also upon what his previous visual-conceptual experience has taught him to see.

Every single person with whom you work has a vastly different set of needs. Fulfilling these needs is one way to make them content and productive. It is your full-time job to listen to these people and mentally document how they are built. This is your most important job. I know the senior VP of engineering is telling you that hitting the date for the project is job number one, but you are not going to write the code, test the product, or document the features. The team is going to do these things, and your job is managing the team.

Libertarianism is grounded in the Principle of Equal Freedom: All people are free to think, believe, and act as they choose, so long as they do not infringe on the equal freedom of others.

Why is it so important—what others have done? Why does it become sacred by the mere fact of not being your own? Why is anyone and everyone right—so long as it’s not yourself? Why does the number of those others take the place of truth? Why is truth made a mere matter of arithmetic—and only of addition at that? Why is everything twisted out of all sense to fit everything else? There must be some reason. I don’t know. I’ve never known it. I’d like to understand.

— Ayn Rand, The Fountainhead
