This month marks the 70th anniversary of the death of Anne Frank, perhaps one of the holocaust’s most recognizable victims. Anne, who died at 15 in the Bergen-Belsen concentration camp, has come to symbolize the suffering endured by millions of Jews at the hands of Nazis during WWII.

The survival of Anne’s diary, which chronicled her time in hiding with her family during the Nazi occupation of the Netherlands, has allowed her words to live on, serving as one of the most indelible reminders of the human tragedy of the war. In memory of Anne’s life, here are 9 inspiring quotes from her diary:

1. “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.”

2. “I don't think of all the misery, but of the beauty that still remains.”

3. "What is done cannot be undone, but one can prevent it happening again."

4. “I don't want to have lived in vain like most people. I want to be useful or bring enjoyment to all people, even those I've never met. I want to go on living even after my death!”

5. “In spite of everything, I still believe that people are really good at heart.”

6. “If we bear all this suffering and if there are still Jews left, when it is over, then Jews, instead of being doomed, will be held up as an example.”

7. "I see the world gradually being turned into a wilderness. I hear the ever-approaching thunder, which will destroy us too. I can feel the sufferings of millions and yet, if I look up into the heavens, I think that it will all come right."

8. “Riches, prestige, everything can be lost. But the happiness in your heart can only be dimmed; it will always be there as long as you live, to make you happy again.”

9. “Whenever you're feeling lonely or sad, try going to the loft on a beautiful day and looking outside. Not at the houses and the rooftops, but at the sky. As long as you can look fearlessly at the sky, you'll know that your pure within and will find happiness once more.”
