The man who has confidence in himself gains the confidence of others.

The saying links inner assurance to social credibility: self-trust tends to project steadiness, clarity, and purpose, which in turn invites others to trust one’s judgment and leadership. Read in a moral-psychological key, it suggests that confidence is not merely private feeling but a communicative posture—people infer reliability from composure and conviction. In a communal or spiritual setting often associated with Schneerson’s teachings, it can also imply that faith in one’s mission (and in one’s capacity to fulfill it) becomes contagious, strengthening collective resolve. The line cautions, however, that confidence functions as a signal; it is most persuasive when grounded in competence and integrity rather than bravado.
