👉 "Pebblehearted" is a phrase that describes someone who seems overly optimistic and believes in something without evidence or proof. It's often used to describe someone who is too confident in their abilities, beliefs, or actions, and may not be able to demonstrate any of these qualities in reality. This term can also refer to a person who has a strong sense of self-importance or pride, as well as an overconfidence that leads them to overlook the limitations of their situation.
