In what scenario might someone 'falter'?

Faltering typically refers to a moment of hesitation, uncertainty, or a loss of confidence, which often occurs during challenging situations. When someone experiences doubt, it can disrupt their focus or commitment to a task, causing them to hesitate or stumble in their performance. This aligns directly with the scenario mentioned; moments of doubt can lead to faltering because they introduce uncertainty and fear, prompting a reevaluation of one's abilities or decisions. In contrast, feeling secure, celebrating successes, or having just completed a task generally create an environment conducive to confidence and continuous progress rather than hesitation.
