I like best to have one book in my hand, and a stack of others on the floor beside me, so as to know the supply of poppy and mandragora will not run out before the small hours.
Don't join the book burners. Don't think you're going to conceal faults by concealing evidence that they ever existed. Don't be afraid to go in your library and read every book...
I suggest that the only books that influence us are those for which we are ready, and which have gone a little further down our particular path than we have yet gone ourselves.
