Excellence/Perfection is not a destination; it is a continuous journey that never ends.
The faculty of imagination is the great spring of human activity, and the principle source of human improvement. As it delights in presenting to the mind scenes and characters more perfect than those which we are acquainted with, it prevents us from ever being completely satisfied without present condition, or with our past attainments, and engages us continually in the pursuit of some untried enjoyment, or of some ideal excellence. Destroy this faculty, and the condition of man will become as stationary as that of the brutes.
The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.
Be a yardstick of quality. Some people aren't used to an environment where excellence is expected.
Some people may have greatness thrust upon them. Very few have excellence thrust upon them.
In every power, of which taste is the foundation, excellence is pretty fairly divided between the sexes.
Persistence is the twin sister of excellence. One is a matter of quality; the other, a matter of time.
It takes a long time to bring excellence to maturity.
The sad truth is that excellence makes people nervous.
The secret of joy in work is contained in one word - excellence. To know how to do something well is to enjoy it.
