"I was right. For you to even manage to do a spell you need to concentrate abnormally high amounts of magic. You must force your wand to work for you, not let it help you. It's not a question of you not having enough magic; the result on Hermione's head shows us that, but that you can't simply concentrate on learning the spells because you can't gather the necessary amount of magic with that wand. Talk to your head of the house, Professor McGonagall, and explain that problem to her. With how much that wand is incompatible with you, you'll never reach your true potential, Longbottom. And one more piece of advice. Ignore what your family tells you. You will never get where you could be if you listen to them telling you that you can't achieve anything.
