Mental toughness encompasses traits like determination, willpower, and perseverance, allowing individuals to overcome fatigue and succeed where others fail. The 40% rule suggests that when people feel exhausted, they have only tapped into 40% of their potential, leaving 60% to be harnessed. Research indicates that brain regions associated with fatigue, particularly the right insula and the dorsal lateral prefrontal cortex, influence effort-related decisions. Often, perceptions of cognitive fatigue do not accurately reflect true capability, which can lead to premature quitting.
Mental toughness, determination, willpower, and perseverance are the key traits that enable individuals to push through fatigue and achieve long-term goals.
The 40% rule, popularized by Dave Goggins, states that when we believe we are exhausted, we are typically only 40% done, with 60% still available.
Neuroscientific research shows that the right insula and the dorsal lateral prefrontal cortex are involved in feelings of fatigue and decisions regarding effort.
Our brain's perception of fatigue can be misleading, suggesting that cognitive fatigue greatly impairs our actual capabilities.
