David Hume

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.

Any kind of creative activity is likely to be stressful. The more anxiety, the more you feel that you are headed in the right direction. Easiness, relaxation, comfort - these are not conditions that usually accompany serious work.
