Confidence is not something that you either have or do not have or have in a certain quantity. Confidence is an attitude. The word confidence means ‘trust’, so whether you are confident or not depends on whether you trust yourself. Sadly, many people have little trust in themselves, little self-belief, and so they will approach new situations and challenges with an attitude that says: ‘I can’t do this’. People who believe in themselves, by contrast, will approach new situations with the attitude: ‘I don’t know whether I can do this, but I am going to have a damn good try’. That is, they do not write themselves off.
