Self confident people are those who know what to do, how to react, when to study and get trained in a particular time. They look simple, calm, less reaction and always deterministic when they do things or perform job.
We should never allow the tough experiences of life to wither our dreams of hope. The way we respond to such conditions is quintessentially important. The moment we lose our self composure we become doubtful about our abilities and our coping skills are inadvertently bogged down . As such, to preserve one's self confidence, one needs to have faith in oneself because by doing so, the whole world accepts him or her. As J. M. Barrie states , “The moment you doubt whether you can fly, you cease for ever to be able to do it.”
Highly confident people are sure of themselves. However; they may make big mistakes by turning up into narcissists who think they are superior to other people.
I came across an interesting article titled ''Power of Confidence: 7 Characteristics of a Confident Person''. In brief, 7 distinguishable characteristics of confident people should be the appropriate: 1. Poise, 2. Eye contact, 3. Firm, 4. Appearance, 5. Tone, 6. Stand up for others and 7. Do what is right (http://www.toptierleadership.com/blog/power-of-confidence-7-characteristics-of-a-confident-person/).
I am not a highly confident person, but I should think that developping self-soothing and relaxation habits would improve my self-confidence. To most scientists, artistic hobbies will do the job!
