To Whom It May Concern:

Learn to appreciate every effort he makes. Remember, he gave up every dream he had, just to grant your request. He gave up the life he used to have just to help you. On top of it, he chose what you wanted for his life, even if he wanted it otherwise. You will never know what you had, until you lose it.

It was all because of how much he wanted you to be proud of him, and how much he really loves you.

You should know it, better than I do.
