Endurance is the ability to sustain over time, to call from ourselves renewed commitment and effort when we are confronted with challenges or hardship. Endurance often requires tolerating discomfort, and may call on us to reach for resources and stamina we are not certain we possess. Endurance means that we remain steadfast even through criticism, monotony, and discouraging odds.
Endurance requires planfulness and balance, not just strength of will. Health and pacing often determine our ability to sustain. This means that we need to take care of ourselves if we care about the long term.
