My Top 10...
1. Allow events to change you.
You have to be willing to grow. Growth is different from something that happens to you. You produce it. You live it. The prerequisites for growth: the openness to experience events and the willingness to be changed by them.
4. Love your experiments (as you would an ugly child).
Joy is the engine of growth. Exploit the liberty in casting your work as beautiful experiments, iterations, attempts, trials, and errors. Take the long view and allow yourself the fun of failure every day.
Allow yourself to wander aimlessly. Explore adjacencies. Lack judgment. Postpone criticism.
10. Everyone is a leader.
Growth happens. Whenever it does, allow it to emerge. Learn to follow when it makes sense. Let anyone lead.
14. Don’t be cool.
Cool is conservative fear dressed in black. Free yourself from limits of this sort.
15. Ask stupid questions.
Growth is fueled by desire and innocence. Assess the answer, not the question. Imagine learning throughout your life at the rate of an infant.
The space between people working together is filled with conflict, friction, strife, exhilaration, delight, and vast creative potential.
Intentionally left blank. Allow space for the ideas you haven’t had yet, and for the ideas
19. Work the metaphor.
Every object has the capacity to stand for something other than what is apparent. Work on what it stands for.
37. Break it, stretch it, bend it, crush it, crack it, fold it.
