The document contrasts confidence with arrogance and humility. Confidence means believing in yourself by understanding your strengths and weaknesses without ignoring flaws or thinking you are superior. This allows you to gain positivity, comfort with your abilities, and support from others to face problems. In contrast, arrogance involves flaunting superiority and ignoring weaknesses, which can lead to ignorance, unhealthy ego, destroyed relationships and lack of support. The key is having confidence without it becoming arrogance.
