When I was an undergrad, I had a professor ( Sr. Nicholas Maltman O.P., PhD.) who started each day by studying archaic Italian for a full hour. My uncle Nicholas Boratynski, held as the family genius, used to start his day at the office by solving a fresh mathematical problem posed to him by his colleagues.
Now I have found what I would do had I their perspicacity and mental drive. I would start each day first thing with a lecture by Douglass Scott. Hard to pull off, since he lives in Boston and I in Seattle. But worth it should one have the opportunity. Blows the carbon right out of the engine. All those gorgeous examples of type and image and color and texture, his deep knowledge and great love of his subject-- by each lecture's end you're ready to tear out the door and attack your own work.
In a design world so often dominated by "personalities," by people who can be harsh or patronizing about student efforts, Scott's dynamic yet even-keel approach makes a place where students can open up and absorb and create without risking life and limb. Of greater value hath no teacher.
