Albus Dumbledore

It does not do to dwell on dreams and forget to live.

Happiness can be found in the darkest of places, if one only remembers to turn on the light.

It is our choices that show what we truly are, far more than our abilities.

Do not pity the dead, Harry. Pity the living, and above all, those who live without love.

Words are, in my not so humble opinion, our most inexhaustible source of magic.
