a vitally important personality trait
As this video from Charisma on Command explains, confidence is rooted in reality, while arrogance positions a person higher or more valuable than they are. Of course, that can feel like an arbitrary scale. To some, you may be the most skilled, talented person in the world, while others may think you’re in over your head.
Fortunately, there are more objective indicators. Confidence, the video explains, acknowledges the contribution of others and will share credit. Arrogance, on the other hand, stems from a place of insecurity and a need to be validated. As such, it will often try to take credit for more than the person really did in an effort to boost themselves up.
On a more simple level, you can even demonstrate confidence over arrogance by being quieter. Arrogance likes to yell. Confidence can be quiet. In this case “loud” can refer to more than just your volume. You can be “loudly” arrogant by craving attention online, being pushy with your coworkers, or just never letting someone else speak, but confidence remains confidence even if it’s not the one in the room getting the most attention.
