The mirror will be moved to a new place tomorrow. Harry, I ask you not to look for it again. If you happen to see it one day, be prepared.

It is useless to indulge in illusory dreams and forget about real life. Remember this. Well, why not put on that amazing invisibility cloak and go back to sleep?

Other quotes:

1. What determines a person's destiny is his choice, Harry, not just his ability.

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

2. People must face reality and cannot live in it all the time. In fantasy.

（Don't dwell on dreams and forget to live.）

Extended information:

Dumbledore character life:

Hobbies: chamber music; ten-pin bowling.

Favorite foods: lemon sorbet, raspberry jam, sour soda (mentioned in "Half-Blood Prince" as the office password), toffee finger cakes, sizzling honey candies, iced lemon juice, Sweets like butterbeer, mead, and of course, piles of cockroaches that the students particularly disliked.

Snacks I don’t like: Bibi’s multi-flavor beans. Because when I was young, I had a bad taste (vomit smell), and when I visited Harry after he was injured, I ate an earwax smell. [8]?

Dislikes: Dementors. So when the Dementors broke into the Quidditch field and Harry fell off his broomstick and was seriously injured, he was very angry and used the Patronus Curse to drive away the Dementors. Ron and Hermione told Harry in the hospital that they had headaches. It was very scary to see Dumbledore so angry for once.
