When one door of happiness closes, another opens. However, we often look at the 1 door so long that we can't see the one that has been opened for us. It's true that we don't know 2 we've got until we lose it, and it's also true that we don't know what we've been 3 until it goes away.

    Giving someone all your 4 doesn't mean that they'll love you back. Don't expect love in return. Just 5 for it to grow in their hearts.

    There are many moments in life when you miss someone so much that you want to bring them into your 6 and hug them for real! Dream what you want to dream, go where you want to go, and 7 what you want to be, 8 you have only one life and one chance to do all the things you want to do.

    Happiness lies in those who have cried, those who have been hurt, those who have searched, and those who have tried, for only they can understand the 9 of their lives. The 10 future will always be based on a forgotten past. You can't go on well in your life until you let your past failure and heartaches go.

    I started playing the piano when I was about eight or nine. But when I got to university, I stopped playing it. I just didn't have enough time and there were so many other things to do.

    When I was little, I thought I should play the guitar like my dad. But later I decided to try something else. I chose the violin. I want to be a musician when I grow up, but my dad says it's difficult to make a living from music. But I don't want to be a doctor like him. It's so boring.

    Nobody likes living near someone like me because when I practice, I make a lot of noise! I''m sorry for that but I have to keep practicing. I have drum lessons every Wednesday and Saturday afternoon, and I practice the drums every evening. I love playing them and now I play in a fantastic band.

    I''ve played the guitar as long as I can remember. I used to play in a subway station to make some money. Now I keep on playing it when I'm free, but I work as a cook in a restaurant to make a living.
