Confidence is a vital aspect of our presence. A confident person will do as they please instead of limiting their actions based on what they think others will believe is appropriate or inappropriate. It turns out that most actions are appropriate. If someone wants to take off their shoes during a class lecture, it is to their benefit to do so and not worry about classmates. If someone wants to do something which puts them in a better position, others will not support it but it is still beneficial to perform the activity.
