Engaging in daily discomfort fosters growth through mental toughness, while self-discipline is cultivated by overcoming smaller challenges. This process includes intentionally doing something difficult, such as fasting when hungry, to strengthen self-control. Employing strategies like goal-setting, mental visualization, positive self-talk, and arousal control enables individuals to resist immediate urges and pursue goals despite discomfort. An effective technique involves adopting an alter ego, allowing a shift in identity to tackle challenges. This recognition that the default self may shy away from hardship helps in overcoming fears and limiting beliefs. Examples like David Goggins' 'Goggins,' Beyonce's 'Sasha Fierce,' and Kobe Bryant's 'Black Mamba' illustrate how altered identities can empower individuals to access their full potential, pushing beyond perceived limits and achieving remarkable feats through the practice of mental toughness.
