“In order to be irreplaceable one must always be different.”

Pleasure in the job puts perfection in the work.

Neither a lofty degree of intelligence nor imagination nor both together go to the making of genius. Love, love, love, that is the soul of genius.

Time you enjoy wasting was not wasted.

I think that God in creating Man somewhat overestimated his ability.

One that desires to excel should endeavour in those things that are in themselves most excellent.

Success is getting what you want; happiness is wanting what you get.
