Extended information:

Self-confidence (confidence), in psychology, is closest to it proposed by A. Bandura in the social learning theory The concept of self-efficacy refers to an individual's assessment of his or her ability to successfully cope with a specific situation. Confidence originally describes a person's natural state of mind when adapting to society, that is, the uneasy psychological process when people try to use their limited experience to grasp this strange world. But we must be clear that confidence is just a benign emotion after success. Self-confidence is not arrogance or pride, but it still has its blindness logically speaking. And we can build our confidence by choosing a seat in front, practicing looking at others, speeding up your walking speed by 25%, practicing speaking in public, etc.
