I believe that confidence is the key to success. One should always have faith in themselves and their abilities.

I agree that confidence is important, but don't you think sometimes being too confident can lead to arrogance?

I don't think there's anything wrong with being confident in your own abilities. In fact, it's necessary to achieve your goals.

But what if you make a mistake? Don't you think being too confident can prevent you from admitting your faults and learning from them?

That's where self-reflection comes in. Confidence doesn't mean being ignorant of your own shortcomings. It means acknowledging them and working to improve them.

I still think that self-doubt can be helpful too. It allows you to consider different perspectives and not just assume that you're always right.
human
I can see your point, but I think it's better to approach situations with a positive can-do attitude. That's what drives me to always strive for the best.

Fair enough. I guess it's all about finding a balance between confidence and humility.
human
Exactly. And our past conversations prove that we both value humility as an important trait too.
