“… one of the most valuable sources of ideas in the visual arts is the resistance of the medium. That’s why oil paintings look so different from watercolors. In principle you could make any mark in any medium; in practice the medium steers you. And if you’re no longer doing the work yourself, you stop learning from this.
So if you want to beat those eminent enough to delegate, one way to do it is to take advantage of direct contact with the medium. In the arts it’s obvious how: blow your own glass, edit your own films, stage your own plays. And in the process pay close attention to accidents and to new ideas you have on the fly. This technique can be generalized to any sort of work: if you’re an outsider, don’t be ruled by plans. Planning is often just a weakness forced on those who delegate.”
