Of people attempting (arduous or dangerous) tasks: brave or spirited.
To teach children to 'have a go' is important to their development and growth. Fear is a typical response to new challenges or experiences. These situations make children feel uncertain, vulnerable, powerless, and anxious. They strip away a child’s sense of security and control. As a result, many children avoid the unfamiliar. They prefer NOT to risk attempting something new, leading to missed opportunities, and setting a negative pattern that can persist into adult life.
