Anne Frank (1929-1945)

Think of all the beauty that's still in and around you and be happy!
Then, without realizing it, you try to improve yourself at the start of each new day; of course, you achieve quite a lot in the course of time. Anyone can do this, it costs nothing and is certainly very helpful. Whoever doesn't know it must learn and find by experience that a quiet conscience makes one strong.
How wonderful it is that nobody need wait a single moment before starting to improve the world.
