In a world full of self-improvement courses, most people lack the willpower and discipline to put what they learn into action. But what if you could develop the skills of discipline, self-worth, fortitude, grit, self-control, and confidence? These qualities, known as mental toughness, are essential for success. However, mental toughness is a perishable skill that requires consistent practice. Many people wonder why they lack confidence and self-esteem while others seem to have it all figured out. This has been a lifelong question for me as well.
