Enduring Energy can be defined as having the ability to sustain physical or mental effort over a long period of time. STAMINA is an important part of this, as it is the capacity to withstand or recover quickly from difficult conditions. It is often associated with physical activity, but can also be used to describe mental strength and resilience. STAMINA is a key component of Enduring Energy, as it allows people to maintain their energy levels for longer periods of time.
