Only madmen, geniuses, and supreme egotists do things purely for themselves. It is easy to buck a crowd, not too hard to march to a different drummer. But it is truly difficult--perhaps impossible--to march only to your own drumbeat. Most of us, whether we are aware of it or not, do things with an eye to the approval of some audience or other. The question is not whether we have an audience but which audience we have.
