There is no excellence uncoupled with difficulties.

What is well done is done soon enough.

Anyone who has achieved excellence in any form knows that it comes as a result of ceaseless concentration.

Human excellence means nothing Unless it works with the consent of God.

There is none who cannot teach somebody something, and there is none so excellent but he is excelled.

Men of genius do not excel in any profession because they labour in it, but they labour in it because they excel.

One shining quality lends a lustre to another, or hides some glaring defect.

It is not sufficiently considered in the hour of exultation, that all human excellence is comparative; that no man performs much but in proportion to what others accomplish, or to the time and opportunities which have been allowed him.

The heart of man does not tolerate an absence of the excellent and supreme.

We measure the excellency of other men by some excellency we conceive to be in ourselves.
