Thanks Susan and Research Analyst. I agree that a person who may appear reserved can have high self esteem and confidence, depending on the environment that they're in.
I am a bit confused about what confidence means. I suspect that it may mean different things depending on the culture. For instance I heard this phrase alot growing up "Speech is silver; silence is golden" My North American experience however, contradicts that belief. The person who tends to talk alot and explain everything, is considered articulate and hence confidence, whereas, the reserved, pensive person is often viewed as slow or not as smart.
I was also wondering if someone can lack confidence and not know it?
Susan, I'll look for your hub on the topic.
