Which of the following clues helps signify when someone is 'in flow'?

When someone is 'in flow,' they experience a sense of time well spent, which indicates deep engagement and immersion in their tasks. This state is characterized by a loss of self-consciousness and a feeling that time flies because the individual is completely absorbed in what they are doing. People in flow often find themselves performing at their best, enjoying the activity for its own sake rather than focusing on external rewards or distractions.

This feeling stands in contrast to distractions or frustration, which can disrupt focus and detract from the overall experience. In a state of flow, individuals typically do not feel frustrated or face difficulties with concentration; instead, they achieve a harmonious balance between their skills and the challenges they face, allowing them to perform with high efficiency and satisfaction.
