Which practice is least likely to help expand the comfort zone?

High levels of stress can hinder the expansion of one's comfort zone because they often lead to feelings of overwhelm and anxiety. When faced with excessive stress, individuals may resort to fight-or-flight responses, which can trigger avoidance behaviors rather than encouraging growth or learning. This intense stress can inhibit the ability to effectively process the experience, diminishing the opportunity for constructive growth.

In contrast, experiencing moderate stress is typically manageable and can introduce challenges that individuals can face and conquer, thereby promoting resilience and confidence. Adequate practice and training allow individuals to build skills and understand their limits, which can gradually expand their comfort levels. Seeking feedback also plays a crucial role, as it provides support and perspectives that encourage improvement and adjustment in one's approach to challenges.
