Watch out for people who think it's embarrassing not to know.

Distinguish open-minded people from closed-minded people. Open-minded people seek to learn by asking questions; they realize that what they know is little in relation to what there is to know and recognize that they might be wrong. Closed-minded people always tell you what they know, even if they know hardly anything about the subject being discussed. They are typically made uncomfortable by being around those who know a lot more about a subject, unlike open-minded people who are thrilled by such company.

It's more important to do big things well than to do small things perfectly.

I notice a difference from the moment I meditate.

In return, society rewards those who give it what it wants. That is why how much money people have earned is a rough measure of how much they gave society what it wanted.

Don't be a perfectionist, because perfectionists often spend too much time on little differences at the margins at the expense of other big, important things. Be an effective imperfectionist. Solutions that broadly work well (e.g., how people should contact each other in the event of crises) are generally better than highly specialized solutions (e.g., how each person should contact each other in the event of every conceivable crisis).

Over time, it also became important for me to share my management principles with the people I worked with because we had to agree on how we should be with each other - and that way is unique. Because the logic behind being radically honest and radically transparent with each other wasn't clear, it had to be spelled out in these principles.
