Gryffindor:

Be not afraid of greatness:

Some are born great,

Some achieve greatness,

And some have greatness thrust upon them.

[Twelth night]

Ravenclaw:

The fool doth think

He is wise

But the wise man

Knows himself

To be a fool

[As you like it]

Hufflepuff:

Love all,

Trust a few,

Do wrong to none.

[All's well that ends well]

Slytherin:

Dreams indeed are ambition,

For the very substance of the ambitious is merely the shadow of a dream.

[Hamlet]
