Gryffindor:

The truth is, some people just aren't going to like you, so you need to balance being civil with them and telling them to go fuck themselves.

Ravenclaw:

If you want friends the world is full of oddballs and misfits, so you just need to show off your weirdness and they will find you.

Hufflepuff:

You need to be a bit more selfish and do what you want to do - you cannot live for others. It's your life, and not living it will make you go crazy.

Slytherin:

Before you get angry at this tiny failure, remember that what is counted as a failure by you is a success to someone else.
