The Paranoia of Working Alone...

“It is a calamity, to say nothing of the time wasted, to labour over details in a poorly conceived design.”
- Sallie Tannahill, B. P’s and Q’s; A Book on the Art of Letter Arrangement.

"The reason is, when there is a hard problem, one has to work a long time and has to be persistent. In order to be persistent, you have got to be convinced that it's worthwhile working so hard, that you're going to get somewhere. And that takes a certain kind of fooling yourself."
-Richard Feynman, Feynman's Rainbow by Leonard Mlodinov
