What is the difference between confidence and over confidence?

Confidence is when you can accurately estimate your potential.
Overconfidence is when you overestimate your potential.

I can do it is confidence.

Only I shall able to do it is over confidence.

A confident person is knowledgeable, has a deep understanding, has sharpened his/her skill sets by repeated practice, and is constantly willing to learn. A confident person is also humble, can acknowledge his/her mistakes, and makes it a point to rectify their mistakes and faults. These qualities build trust and make him/her success in life.

Whereas, An overconfident person, on the other hand, is blind to his/her mistakes and faults. He/she cannot accept their shortcomings and assume that they know the best. Hence they stop learning and slowly but surely stop being successful in their chosen path.

Confidence shows fact and knowledge.

Over-confidence shows a fake attitude.

Confident : I can do something.

Over confident : I can do everything.

IF I say, I can do this work then this is a confidence.

In a particular situation, If I say this work is only done by me then this is an overconfidence.

In my opinion, Confidence is like saying ' I think I am a deserving candidate for the job' whereas someone with overconfidence would say something like 'I think I'm the only best candidate available for the job'.

Confidence means a positive self-believe I can do it well.
Overconfidence means I can only do this no one can do this except me.

Confidence is the belief in your abilities and skills. It allows you to take on challenges, make decisions, and engage with others positively.

For example, when you prepare well for a presentation, your confidence helps you speak clearly and effectively.

On the other hand, overconfidence is an excessive belief in your abilities, often leading to mistakes or poor decisions. It can make you underestimate risks or overlook important details. For instance, if someone thinks they can ace an exam without studying because they feel overly confident, they might not perform well.

In summary, confidence is healthy and necessary for success, while overconfidence can lead to negative outcomes.

Confidence is based on facts and knowledge. Overconfidence is based on speculation.
There is a small difference between confidence and overconfidence.
Yes, I can do this work, is self-confidence but only I can do this work is overconfidence or you can say that confidence is an internal belief that I am the right person for this job.
Overconfidence is thought that I am only the right person for this job.
