How has the individual learned to manage their impatience?

The correct answer highlights the idea that managing impatience often requires a shift in perspective or approach to tasks. When someone becomes less detail-oriented, they may allow themselves to let go of excessive focus on minor elements, which can be a significant source of frustration and impatience. This change in mindset can lead to a more relaxed view on progress and outcomes, ultimately reducing a person's feelings of impatience.

In contrast, strategies like practicing meditation, setting deadlines, or working on group projects can also help with patience but do not directly address the foundational skill of being less meticulous about details. Meditation might promote overall mindfulness, setting deadlines could increase focus, and group projects provide collaboration that may distract from impatience, but these approaches do not specifically target the underlying aspects of detail orientation that can provoke impatience. Thus, the choice of becoming less detail-oriented directly aligns with a method for effectively managing impatience.
