Eleanor Roosevelt said this quote

The encouraging thing is that every time you meet a situation, though you may think at the time it is an impossibility and you go through the tortures of the damned, once you have met it and lived through it you find that forever after you are freer than you ever were before. If you can live through that, you can live through anything. You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face.
