Those with a high level of confidence may have as many or more weaknesses than those with low self-esteem. The difference is this; instead of dwelling on their handicaps, they compensate for them by dwelling on their strengths.
There is not really any courage at all in attacking hoary or antiquated things, any more than in offering to fight one's grandmother.

The only true free-thinker is he whose intellect is as much free from the future as from the past.
Having courage does not mean that we are unafraid. Having courage and showing courage mean we face our fears. We are able to say, 'I have fallen, but I will get up.'
