Life can be compared to the construction of a tunnel; we are often obstructed by solid rocks. Invincible thinking works as the powerful drill to break through these rocks. When we practice this thinking, we will never feel defeat in our life. Invincible thinking is based on the practical theories that bridge self-reflection and development, and it exerts a great power. By reading, savoring and practicing the thoughts in this book, and by using the thoughts as your own power, you will be able to declare that there is no such thing as defeat--only victory.
