Do not depend on the hope of results.
When you are doing the sort of work
you have taken on, you may have
to face the fact that your work will be
apparently worthless and even achieve no
worth at all, if not perhaps results opposite
to what you expect.
As you get used to this idea, you will
start more and more to concentrate not on
the results, but on the value, the rightness,
the truth of the work itself.
