The most optimistic and hence the most confident person I know of is Simon Sinek. His work around leadership, motivation as well as optimism is inspiring to the core.

Simon is the creator of the Golden Circle, the framework to help you realize your own WHY or PURPOSE in life.

Aside from this his work around comparing life as well as business with the infinite game is indeed praiseworthy.

Finally the learning around Optimism and knowing that it the most positive human emotion really energizes me. Hence I feel Simon is the most confident person I have ever come across.
