How could us be more confident? Young people are increasingly feeling unsure of themselves in current society. Despite we’ve had access to way more resources than our counterparts who lived hundreds of years ago, we are not happier or more confident than them, if not worse. Why is that? Before we answering that question we have to know what is confidence and which factor is impeding it. When we show no confidence in face of some challenging tasks, our friends are very likely to comfort us by just saying “be confident!” or “believe yourself.” And that those words usually turns out to be very unhelpful . Scientific studies may take confidence as a state of mind, therefore prescribing some advises for those who lack confidence to do some mind trainings such as meditation. The concept, “confident”, is not static through out the human history. In ancient Greece, people didn’t care about confident but something similar, that was brave . They regarded brave as a kind of moral ethics, and they would believe brave combating in the battle field is the most honor thing a man could do. While modern people are taking confidence as an ability, the ancient Greek people had regarded it as the thing they must do for honor, which was ethics. Some philosopher believe that the opposite aspect of confidence is fear. People feel fear when the challenge that they are facing are overwhelming. It could be engendered through a temporal and specific task or a lasting and universal social stress, while the increasing of the latter one is the reason why modern people are feeling less confident. Psychology shows that the fearing or uncomfortable emotion or are the self-protecting mechanism everyone has in their body. We feel bad every time we are frightened by the stress around us. Such that we could become more confident if we had less fear. Sounds like a cliché . But it would make a change when know the way to decrease our fear. Fear comes from the unknown. We will feel fear when walking in darkness. We are terrified if we got some difficult tasks we don’t know how to do. We tend to hesitate before making a choice of which we have never made. Nothing could help but knowledge. Knowledge could help us know more about the information about the issue at hand. Knowledge may give us a clearer view of what is around us. And most importantly, knowledge make us understand ourselves. Anyone who ever want to be free from anxiety should embrace knowledge.
