"There are good and bad times, but our mood changes more often than our fortune." — Thomas Carlyle

Blessed is he who has found his work; let him ask no other blessedness.

Old age is not a matter for sorrow. It is matter for thanks if we have left our work done behind us.

What we become depends on what we read after all of the professors have finished with us. The greatest university of all is a collection of books.

Permanence, perseverance and persistence in spite of all obstacles, discouragements, and impossibilities: It is this, that in all things distinguishes the strong soul from the weak.
