You gain strength, courage and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, "I have lived through this horror. I can take the next thing that comes along." … You must do the thing you think you cannot do.
One thing life has taught me: if you are interested, you never have to look for new interests. They come to you. All you need to do is to be curious, receptive, eager for experience. And there's one strange thing: when you are genuinely interested in one thing, it will always lead to something else.
If you tremble with indignation at every injustice, then you are a comrade of mine.
