We are not born with it. We can learn it.
Arrogance tries to mask itself as being confident, knowing it all. Arrogance is not a skill. We can make money being arrogant by acting successful. The end goal of arrogance revolves around manipulation, fear, bullying, and a race toward entropy. Arrogant people only care about themselves. We are not born arrogant.
The most important action we need to succeed in business and education is confidence. Confident people survey everyone in a room, concerned with all people and manner of learning, and are present with them. Confidence has a bit of appropriate fear and awareness attached to self reflection. It takes practice. Confidence responds, willing to learn and become better.
We can be confident.
