So I have to admit that I don't keep a sketchbook anymore. I did as an undergrad, and I frantically scribbled down evrything I saw that was compelling or any thought that popped into my head. The thing is, every time I write something down or sketch out an idea, I ususally forget about it. I just stopped keeping one and I seem to act on more of my ideas than I ever did when I was writing them down all the time. Someone once told me a story about when Corb met Einstein. Corb kept copius notebooks and assumed that Einstein did the same. He asked Einstein about it and Einstein responded that he did not keep any notebooks because if he had worthwhile thought he would remember it. Now, that story may be urban legend, but it rings true with me some days.
Now, I know this is near criminal in the minds of many architects, professors and students, but I don't think drawing is that important any more. To me, the mythology about drawing is a result of architects building a mythology around what they were going to have to do for the rest of their lives. That is, at some point in the recent past if you were an architect you spent most of your time putting pencil to paper: drafting. Those long hours at the drafting board had to have some meaning, so we built up a religion around drawing and its power to convince ourselves that what we do with our time is more that just "work". That is why so many architects react so poorly to "computer" drawings. They have been distanced from the means of production of buildings.
I am intentionally overstating the case to get some opinions. So tell me what you think. Do you keep a sketchbook? Why or why not? Do we need our own mythology around the computer to help us get through a career of staring at one?
