In many cases, thinking that we are limited is itself a limiting factor.

I've noticed this with self confidence as well. Its interesting because suppose there were two people who were both identical in capability - the one with confidence will do much better. He/She will put ideas out, will come across as more impressive to other people, and in the long term grow faster than the unconfident person because of it...

I mention it because I was surprised when I realized that success is not just intelligence, hard work, and social interaction, but that success is also intertwined with general personality characteristics, like confidence.

Confidence plays a massive role in success. If you can balance the fine line between confidence and arrogance you'll find more doors open up to you than ever before.
