What is the difference between confidence and over confidence?

Confidence is "I can do this work" and overconfidence is "only I can do this work" like we are here for the job interview and if I think that "I will get this job is my confidence but if I think "only I will get this job is my overconfidence".

Respected sir/ mam.

In my point of view, confidence is based on Facts and Figures but over confidence is based on speculation.

First, we analyse that work, then decided we can do that work this is confidence.

Without analysing that work then decided we can do that work this is overconfidence.

There is a small difference between confidence and overconfidence. Confidence means I can do that. Over confidence means Only I can do that.

This small difference leads to change one's life totally. In life we put confidence towards you, then you can achieve anything, with over confidence one can achieve nothing.

Confidence means: Our hard work with us. And no one can change this that's an internal feeling. I am right for this opportunity I can do this. Everyone can do this. But. I am fue well from other that is confidence.

No one can do this without my help. And for that. I am the best, that is not internal that's a feel the yourself very intelligent and other are, nothing. that's overconfidence.

Confidence is - l am right.

Overconfidence is - I am always right.

Well, according to me in short confidence means "I can do this work' and overconfidence means "ONLY I can do this work' and also confidence more than required is harmful and that's called overconfidence. That's the difference.

If I will say, "I can do it" this is confidence. And if I will say "only I can do it" it's overconfidence.

I am an engineer. This is confidence.

I am a good engineer this is overconfidence.

I can do this work is confidence.

I am only the person can do this work is over confidence.

In my opinion, confidence is to prepare before attending an interview and then see a possibility of getting the job while overconfidence is to attend an interview without preparation and still expecting oneself to get the job.

Confidence I can climb on mountain Everest.

Over confidence only I can climb on mountain Everest.

That's all.
