When I was teaching I often said to students that you are trying to be too creative, don't be too creative, because there is so much already in what you are making, you don't need to do very much. You just need to do a little bit, and that is a lot.
When I started teaching in the late 60s, in a time of student revolutions and changes, they changed in question of society and authority.
If you were really interested in being creative in teaching, it was possible to try new methods and that was really what we did in Goldsmiths - we used the freedom of the time.
