Non nobis solum nati sumus.

(Not for ourselves alone are we born.)

Nescire autem quid antequam natus sis acciderit, id est semper esse puerum. (To be ignorant of what occurred before you were born is to remain always a child.)

Nemo est qui tibi sapientius suadere possit te ipso: numquam labere, si te audies.

(Nobody can give you wiser advice than yourself: if you heed yourself, you'll never go wrong.)

The man who commands efficiently must have obeyed others in the past, and the man who obeys dutifully is worthy of being some day a commander

Gratitude is not only the greatest of virtues, but the parent of all the others.

For a tear is quickly dried, especially when shed for the misfortunes of others.
