It is easier to do many things than to do one thing continuously for a long time.
Our minds are like our stomachs; they are whetted by the change of their food, and variety supplies both with fresh appetites.
The pretended admission of a fault on our part creates an excellent impression.
We excuse our sloth under the pretext of difficulty.
We must form our minds by reading deep rather than wide.
Marcus Fabius Quintilian (35 - 90) Roman orator
