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.
What is the point of worrying oneself too much about what one could or could not have done to control the course one’s life took?

And if some of us are prepared to sacrifice much in life in order to pursue such aspirations, surely that is in itself, whatever the outcome, cause for pride and contentment.
