Every university…seem[s] to reassure you that ‘it doesn’t matter what you do, as long as you do it well.’ That is completely false. It does matter what you do. You should focus relentlessly at something you’re good at doing, but before that you must think hard about whether it will be valuable in the future.

In the most dysfunctional organizations, signaling that work is being done becomes a better strategy for career advancement than actually doing work (if this describes your company, you should quit now).

Our economy is broken. I'm not a politician, but neither is Donald Trump. He is a builder, and it's time to rebuild America.

For Hamlet, greatness means willingness to fight for reasons as thin as an eggshell: anyone would fight for things that matter; true heroes take their personal honor so seriously they will fight for things that don’t matter.

You'll attract the employees you need if you can explain why your mission is compelling: not why it's important in general, but why you're doing something important that no one else is going to get done.

All failed companies are the same: they failed to escape competition.
