Which of the following is NOT considered a virtue of service before self?

Courage, integrity, selflessness, and respect for others are all key virtues emphasized in the concept of service before self. However, the virtue specifically associated with the idea of putting others before oneself primarily focuses on selflessness and respect for others within a service framework.

Courage is often associated with individual bravery and willingness to face fear, danger, or adversity. While it's a highly regarded quality in the context of service, it does not directly embody the self-sacrificing aspect implied by "service before self." The philosophy of service before self is primarily about prioritizing the needs and welfare of others, which is more closely represented by selflessness and respect.

In summary, while courage is commendable and vital in many contexts, it does not align with the core principle of altruism that service before self embodies as clearly as the other virtues do.
