Bruce Mau has a nice collection of idead [via Shrikant Patil]. The 3 that I liked:
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.
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.
Harvest ideas. Edit applications. Ideas need a dynamic, fluid, generous environment to sustain life. Applications, on the other hand, benefit from critical rigor. Produce a high ratio of ideas to applications.
