Mental toughness is the ability to stay focused, motivated, and calm under pressure, regardless of the circumstances. It is the mental resilience that allows you to push through difficulties, adapt to challenges, and keep moving forward despite setbacks. Resilience, the capacity to recover from difficulties, is a core aspect of mental toughness, and it plays a crucial role in self-discipline. Without resilience, self-discipline can become easily compromised by obstacles and failures. Together, mental toughness and resilience form the backbone of long-term success, perseverance, and productivity.
