The Harry Potter series is full of big ideas and great advice, which makes for great quotes. This is one of my favorite because it gets at the moral heart of the series: that we must make an effort, possible even make sacrifices, in order to do the right thing.

Dark times lie ahead of us and there will be a time when we must choose between what is easy and what is right.  —Albus Dumbledore in Harry Potter and the Goblet of Fire by J.K. Rowling
