The expression "sure of yourself" means that you are confident and believe in your abilities or decisions. You can use this expression when you are describing someone who is very confident in themselves or when you are talking about your own confidence. For example, you can say "He is always sure of himself in any situation" or "I am sure of myself when I speak in public." It is important to note that being sure of yourself does not mean being arrogant, but rather having a healthy level of self-confidence.
