All work and no play makes Jack a dull boy

All work and no play makes Jack a dull boy is a proverb. It means that without time off from work, a person becomes both bored and boring.

Some writers have added a second part to the proverb, as in Harry and Lucy Concluded (1825) by the Irish novelist Maria Edgeworth:

All work and no play makes Jack a dull boy,

   All play and no work makes Jack a mere toy.
