An investment in knowledge pays the best interest.

The doorstep to the temple of wisdom is a knowledge of our own ignorance.

Tell me and I forget. Teach me and I remember. Involve me and I learn.

Life's Tragedy is that we get old to soon and wise too late.

A life of leisure and a life of laziness are two things. There will be sleeping enough in the grave.

Dost thou love life? Then do not squander time, for that is the stuff life is made of.

To lengthen thy life, lessen thy meals.

If you would be loved, love, and be loveable.
