Never suffer youth to be an excuse for inadequacy, nor age and fame to be an excuse for indolence.
I like the word `indolence.' it makes my laziness seem classy.
Indolence is a delightful but distressing state; we must be doing something to be happy.
There are two main human sins from which all the others derive: impatience and indolence. It was because of impatience that they were expelled from Paradise, it is because of indolence that they do not return. Yet perhaps there is only one major sin: impatience. Because of impatience they were expelled, because of impatience they do not return.
The failure of the mind in old age is often less the results of natural decay, than of disuse. Ambition has ceased to operate; contentment bring indolence, and indolence decay of mental power, ennui, and sometimes death. Men have been known to die, literally speaking, of disease induced by intellectual vacancy.
