Helen Keller said this quote

“ There are times when I long to sweep away half the things I am expected to learn; for the overtaxed mind cannot enjoy the treasure it has secured at the greatest cost. ... When one reads hurriedly and nervously, having in mind written tests and examinations, one's brain becomes encumbered with a lot of bric-a-brac for which there seems to be little use. At the present time my mind is so full of heterogeneous matter that I almost despair of ever being able to put it in order. Whenever I enter the region of my mind I feel like the proverbial bull in the china shop. A thousand odds and ends of knowledge come crashing about my head like hailstones, and when I try to escape them, theme goblins and college nixies of all sorts pursue me, until I wish – oh, may I be forgiven the wicked wish! – that I might smash the idols I came to worship. ”
