“The fact that you can feel pain like this is your greatest strength.”

“There is no shame in what you are feeling, Harry,' said Dumbledore's voice. 'On the contrary... the fact that you can feel pain like this is your greatest strength.”

“You care so much you feel as though you will bleed to death with the pain of it.”

“The knowledge that you have emerged wiser and stronger from setbacks means that you are, ever after, secure in your ability to survive. You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for all that it is painfully won, and it has been worth more than any qualification I ever earned.”

“Numbing the pain for a while will make it worse when you finally feel it.”

“You have to resign yourself to the fact that you waste a lot of trees before you write anything you really like, and that's just the way it is. It's like learning an instrument, you've got to be prepared for hitting wrong notes occasionally, or quite a lot, cause I wrote an awful lot before I wrote anything I was really happy with. And read a lot. Reading really helps. Read anything you can get your hands on.”

“Play to your strengths.""I haven’t got any," said Harry, before he could stop himself."Excuse me," growled Moody, "you’ve got strengths if I say you’ve got them. Think now. What are you best at?”
