Cast thy bread upon the waters: for thou shalt find it after many days.

If you wait for perfect conditions, you will never get anything done.

Truly the light is sweet, and a pleasant thing it is for the eyes to behold the sun: But if a man live many years, and rejoice in them all; yet let him remember the days of darkness; for they shall be many. All that come is vanity.

There is nothing new under the sun.

Be not slow to visit the sick.

Give not over thy soul to sorrow; and afflict not thyself in thy own counsel. Gladness of heart is the life of man and the joyfulness of man is length of days.
