Overconfidence makes you spend more than necessary

[GeorgeJohn]

To be overconfidence is good, and before someone to be overconfidence in something, it means he knows the rudiment of the things...I want to inform us that, in some certain online processing documents of any kinds, needed for anyone who wants to process it to come to their server and process it before it will go true or be successful..anything that make you to process it out of the jurisdiction of the server, automation error most occur...The person you're using as point of illustration might know the process more better, but due to it did it out off the server the government workers are using to process details, it may likely to be intercepted in processing...

In fact, if there is no confidence then courage to take first step often does not come. Problem will arise only when we pretend to be overconfident. If someone think he is wise despite not having enough knowledge then he is a fool.  Same goes for that person you mentioned here. He did job despite not having necessary knowledge. And that is where he went wrong.

However, I will not belittle his self-confidence. Making mistake is not problem either. This will allow him to learn subject better and avoid repeating error in future. It is true that relying on others for every task would make thing easier for us. But I would never be able to do that work myself. I would always have to remain dependent on others.
