Laudator Temporis Acti

Sirach 30.21-25 (tr. G.H. Box and W.O.E. Oesterley):

[21] Give not thy soul to sorrow,
    And let not thyself become unsteadied with care.
[22] Heart-joy is life for a man,
    And human gladness prolongeth days.
[23] Entice thyself and soothe thine heart,
    And banish vexation from thee:
For sorrow hath slain many,
    And there is no profit in vexation.
[24] Envy and anger shorten days,
    And anxiety maketh old untimely.
[25] The sleep of a cheerful heart is like dainties,
    And his food is agreeable unto him.

The same, tr. Patrick W. Skehan (with slightly different numbering):

[21] Do not give in to grief
    or afflict yourself with brooding;
[22] Gladness of heart is the very life of a person,
    and cheerfulness prolongs his days.
[23] Distract yourself, renew your courage,
    drive resentment far away from you;
For grief has brought death to many,
    nor is there aught to be gained from resentment.
[24] Envy and anger shorten one's life;
    anxiety brings on premature old age.
[27] One who is bright and cheery at table
    benefits from his food.
