He who labours not, cannot enjoy the reward of labour.

Man cannot aspire if he looked down; if he rise, he must look up.

He who never made a mistake, never made a discovery.

He who labours, prays.

Labour may be a burden and a chastisement, but it is also an honour and a glory. Without it, nothing can be accomplished.

It is idleness that is the curse of man - not labour. Idleness eats the heart out of men as of nations, and consumes them as rust does iron.
