Bulletpoint take-aways from the end of the presentation:

• Numbers on the screen are representations of the real world.
• Look at the real world, not just representations.
• Walk around what you want to learn about.
• In doing creative work, do not start your day with addictive time-vampires such as The New York Times, email, and Twitter.
• All scatter eye and mind, produce diverting vague anxiety, clutter short-term memory.
• Instead begin right away with your work.
• Many creative workers have independently discovered this principle.
