Stock your mind

"Stock your mind. Stock your mind. It is your house of treasure and no one in the world can interfere with it. If you were to win the Irish Sweepstake and brought a house, would you fill it with bits and pieces of rubbish? Your mind is your house and if you fill it with rubbish from the cinemas it will rot into your head. You might be poor, your shoes might be broken, but your mind is your palace."
- Frank McCourt (Angela's Ashes)
