Work Smart

In order that people may be happy in their work, the three things needed are:
They must be fit for it,
They must not do it too much of it,
They must have as sense of success in it,
- not a doubtful sense, such as needs some testimony of others for its confirmation, but a sure sense and rather knowledge, that so much work has been done well and fruitfully done, whatever the world may say or think about it.
