What guideline for building confidence involves seeking support from others?

Seeking support from others is a crucial guideline for building confidence because external encouragement can significantly influence an individual's self-perception and performance. When individuals surround themselves with positive influences, such as supportive friends, family, or mentors, they are more likely to receive constructive feedback and emotional reinforcement. This support helps to create a positive feedback loop, where the individual feels more validated and confident, thus encouraging them to engage in speaking opportunities more frequently. Positive support can include understanding listeners, constructive criticism, and celebrating small achievements, all of which contribute to a stronger sense of assurance in one’s abilities. In contrast, the other options, while beneficial in their own right, do not specifically focus on the aspect of seeking and receiving external support, which is essential for fostering confidence in public speaking or any performance-related task.
