“「Vision is not seeing, but believing.」”

“「Whether you think you can, or you think you cannot, you are right.」”

“「The impediment to action advances action. What stands in the way becomes the way.」”

“「The block of granite which was an obstacle in the pathway of the weak became a stepping-stone in the pathway of the strong.」”

“「Success is to be measured not so much by the position that one has reached in life as by the obstacles which he has overcome」”

“「In order to succeed people need a sense of self-efficacy to struggle together with resilience to meet the inevitable obstacles of life」”
