Stamina and endurance aren’t necessarily the same. Endurance defines the physical ability to keep performing at maximum output, throughout one race. Stamina defines the ability with which a racer can perform throughout the entire season or championship. Meaning, stamina entails physical capacity, as well as mental capacity.
Obviously, physical and mental capabilities go hand in hand and reinforce one another.
Stamina, the mental capacity to endure, time and time again, is the singe most important characteristic for entrepreneurs. There is no such thing as overnight success.
Throughout the season, you might win some races, you might lose some. The capacity with which entrepreneurs refuse to give up is crucial.
