It's important for celebrities, environmentalists and world leaders to continue to increase education and eco-awareness through the forums provided to them naturally by virtue of being famous. Take inspiration from these words of wisdom from a Nazi-era teenager and concentration camp victim: "how wonderful it is that nobody need wait a single moment before starting to improve the world."

I don't have much in the way of money or worldly possessions, I'm not beautiful, intelligent or clever, but I'm happy, and I intend to stay that way! I was born happy, I love people, I have a trusting nature, and I'd like everyone else to be happy too.

Sometimes I think God is trying to test me, both now and in the future. I'll have to become a good person on my own, without anyone to serve as a model or advise me, but it'll make me stronger in the end.

The reason for my starting a diary is that I have no real friend.

It's really a wonder that I haven't dropped all my ideals, because they seem so absurd and impossible to carry out. Yet I keep them, because in spite of everything I still believe that people are really good at heart.

Ordinary people don't know how much books can mean to someone who's cooped up.

Everyone thinks I'm showing off when I talk, ridiculous when I'm silent, insolent when I answer, cunning when I have a good idea, lazy when I'm tired, selfish when I eat one bite more than I should.
