Your best preparation for a good day's work: a good night's sleep.

Contrary to the manner in which a great many people seem to regard sleep, sleep is not a waste of time. Inadequate sleep, let alone chronic sleep deprivation and actual sleep disorders, leads to diminished quality of work and loss of productivity. As far as caregivers are concerned, inadequate sleep can affect dangerously their ability to function in critical situations. On the other hand, adequate sleep is needed if one is to function at one's potential best and sufficient sleep is also an effective hedge against the encroachment of job stresses. For one who is occasionally unable to get sufficient sleep, there are steps to be taken to improve the ability to rest. A good night's sleep invariably precedes a good day's work.
