What are some of the ways to practice confidence/ self-confidence?

In many Buddhist doctrines, confidence or self-confidence is thought as a virtue. I am still struggling to see how it does not contradict with arrogance or pride. A few expansions are: - "confidence in the Buddha, Dhamma, Sangha" - "An attitude of gladly engaging in wholesome activities, and it functions to cause one to accomplish wholesome or virtuous actions" - This seems synonymous to confidence. I would be grateful if anyone could provide other perspective on self-confidence and how it should be viewed in light of Buddhism, in particular Tibetan Buddhism. And also, what are the practices that one can do to have the virtue?
