Ovid

Nescio quid sit amor; an sit idoneus armis.

I see and approve the better course, but I follow the worse.

Everything changes, nothing perishes.

Dripping water hollows out stone, not through force but through persistence.

Note too that a faithful study of the liberal arts humanizes character and permits it not to be cruel.

If you wish to be loved, love.

Take away the cause, and the effect ceases.

The mind is its own place, and in itself can make a heaven of hell, a hell of heaven.

Be patient and tough; this pain will serve you one day.

The harvest is always more abundant in other people's fields.

What is love? It is a thing that is not, and yet it is.

A new thing always brings a new life.

The burden which is well borne becomes light.

Nothing is stronger than habit.

Every lover is a soldier.

The greatest minds are those who can be happy in themselves.

A man learns more from his mistakes than from his successes.

If you want to be a good old man, be a good young man.

By the slow process of time, the hardest things are softened.

Begin, be bold, and venture to be wise.
