I love that Toronto is demonstrating that a big, highly diverse, multicultural city can actually work and work well, if its residents have the attitude of Torontonians.

In order to have a hope of creating better answers, we need to deeply understand the logic of the opposing answers. That means thinking about how we think about both models - not just do we like one versus the other. Rather we have to ask: How do I think each model produces the results that it does? Metacognition, thinking about thinking, builds up our capacity to do that and to play with opposing ideas - and new models - in real time.

The ability to face constructively the tension of opposing ideas and instead of choosing one at the expense of the other, generate a creative resolution of the tension in the form of a new idea that contains elements of the opposing ideas but is superior to each.

I always have a pad of paper and a pencil within reach, to catch on the wing this turn of phrase which strikes me as felicitous, that idea which I hope to be able to examine more closely in the light of day.

When it comes to innovation, business has much to learn from design. The philosophy in design shops is, 'try it, prototype it, and improve it'.

Design isn't just about making things beautiful; it's also about making things work beautifully.

You need to be uncomfortable and apprehensive: True strategy is about placing bets and making hard choices. The objective is not to eliminate risk but to increase the odds of success.
