Life is like building a tunnel; it's arduous and time-consuming. We often encounter setbacks, and we may sometimes feel overwhelmed by the solid rock that stands before us. Invincible thinking is the powerful drill that lets us drill through this rock; it's the dynamite that lets us open a crack in the mountain of difficulties. When we practice invincible thinking, we learn both from our successes and failures and cultivate the strength to create our own future, and share that wisdom with those who will follow our footsteps. In this book, Ryuho Okawa lays out the principles of invincible thinking that will allow us to achieve long-lasting triumph. This powerful and unique philosophy is not only about becoming successful or achieving our goal in life, but also about building the foundation of life that becomes the basis of our life-long, lasting success and happiness. With the mindset and attitude of invincibility, we can turn failures into successes, adversities into opportunities, and mistakes into great accomplishments. When we learn from every experience and transform it into wisdom, we will never know defeat, only triumph in life.
