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.
- 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'?
