What is the difference between confidence and over confidence?

Confidence = A player in a football match thinks that he can score the Goal with the support of his football team.

Over confidence = A player in a football match thinks that he can score the Goal without the support of his football team.

There's a thin line between confidence and overconfidence. If I say something and I proved it right then it is confidence but if I could not prove it and then verbally saying the opposite that's called overconfidence.

In my point of view, I can do is confidence, only I can do is over confidence.

When you do something about which you're sure, it is confidence.

When you do something about which you're not sure and giving statements based on emotions, its overconfidence.

Confidence - Leads to Satisfaction.

Over Confidence - Leads to Dissatisfaction.

Confidence is the belief that one can have faith and Overconfidence is the quality of being too confident.

If we decide whether we can do particular work or not after analysing is confidence, if we decide we can without analysing it is Overconfidence.

Let me give an example:.

Suppose I have attended the particular interview and if I say I will get the job it is confidence because I know how I performed.

But if I say only I will get the job, no one can do better than me it is Overconfidence because I don't know how the rest of them performed, might be someone else has performed well.

If a person is confident then he or she is increase his or her efforts towards his or her goals but if a person is overconfident then he or she decrease his or her efforts towards his or her goal. If a person is confident then he or she is more determined towards his or her goal but if a person is overconfident he or she will take his or her goal very lightly.

Confidence:It is I can do any thing by hardwork.

Over confidence:It is I can do any thing without hard work.

Confidence Is I can do that job.

Overconfidence is No one can do that job other than me.

Confidence is something that gives you courage to tackle difficult situations with a cool mind.

On the other hand, Over confidence gives you prior feel of success which restrict one to make efforts to accomplish a task.
