Julian Shapiro inspires me with his visuals (the design of his website is beautiful) and words. I like the notion of "Challenging our Defaults", and to counter that with learning about "Good Enough" as a mental model to avoid analysis-paralysis. I like this quote by Channing Allen that Julian added: "When you view the world as a series of outputs, you form opinions. But when you view the world as a series of systems, you form strategies." -- This can help you deal with complicated situations at work and in life. Look at the incentives the system created that led people acting in a certain way.
