Think how slow would be your progress in learning without printed books: you could study only manuscripts, and those necessarily must be very few in number. Learn from this to value your books, and always handle them with care.
Nothing seems to me so likely to make people unhappy in themselves and at variance with others as the habit of killing time.
What greater bliss than to look back on days spent in usefulness, in doing good to those around us.
Pleasures take to themselves wings and fly away; true knowledge remains forever.
No blessing, no good, can follow in the path trodden by slavery.
My wish is to be known only thru my work.
