Of course we all know that it is a subtle difference between confidence and self-confidence. But I could not find the question asked (let alone answered) on various sites before; hence I am asking this question.
I am not talking about confidence in others as in "she had great confidence in her mother" or"he had implicit confidence in the bureaucracy", but where confidence obviously refers to self.
Random Examples:
- She played the violin with great confidence.
- He batted with tremendous confidence though it was his first Test match.
- We must always approach life with confidence.
- The management course helped them to develop leadership skills and self-confidence.
- It was a measure of his self-confidence that he left the job before finding another.
- He was very impressed with her boldness and self-confidence.
My question is whether we could use confidence and self-confidence interchangeably wherever confidence obviously refers to self and not others? If not, what is the 'fine difference'?
