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.

Always remember those things that tend to strengthen and improve your understanding. You cannot learn without attention, neither retain those lessons that you have once learnt without frequently reflecting upon and reviewing them in your mind; by this means, things long past will remain impressed upon your memory.

It is of no use to commit whole pages to memory, merely to recite them once without hesitation; you must think of the meaning more than the words - of the ideas more than the language.

As you have learnt something of time, value and make a proper use of it. Once past, it knows no return; how necessary, then, that you spend it in improving your mind and fitting it for future happiness and usefulness.

With care and patience, people may accomplish things which, to an indolent person, would appear impossible.

A camera is a tool for learning how to see without a camera.
