Fear is like being shot out of a cannon. Imagine a car has fallen on someone I love—I get this clear, calm, intense bolt of energy. In that heightened state, I could lift the car off them (as has happened before in rare cases). Anxiety, on the other hand, is like being haunted. You never actually see what's scaring you—it's just a story in your head that never goes away.

How would one expect society to develop 'actualisation' and 'esteem' driving characteristics (economic growth and spending) when the basic 'physiological' and 'safety' needs (food security, employment, health, property) are not met.

Similar to the 'use it or lose it' principle that applies to muscles, our brains engage in a nightly routine that stimulates thoughts and ideas not typically relied upon during the day. This built-in process keeps our thinking adaptive and nimble, fostering divergent thoughts and offering an evolutionary advantage.

You will never find opportunities in your comfort zone, you have to push yourself. The unknown is where you will always find opportunity. When you lose your own money, it hurts, it makes you careful, but you cannot let it take the mojo… the hunger out of you.

The world is so impossibly complex, beautiful and fragile and this gives us so many questions that we should ask. Curiosity is powerful, and that is the heart of TED.
