Here's an insight that I've had about success: You can't be successful at everything. We hear a lot of talk about work-life balance. Nonsense. You can't have it all. You can't. So any vision of success has to admit what it's losing out on, where the element of loss is. And I think any wise life will accept, as I say, that there is going to be an element where we're not succeeding.

The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.

The true measure of success is not just profit, but the positive legacy we leave for future generations.

Whenever you find yourself on the side of the majority, it is time to pause and reflect.
