Interesting, the "reality" described are examples of fixed beliefs - who decides what someone's potential is? Who decides what someone's precious time and resources are? In other words "the reality" is singular, fixed, immovable. Examples: "Face facts, you cannot win the 100 meters" "Don't ignore reality, you have no ability to win races". The article seems to imply that people with low fixed beliefs have been told by others what their potential is, and what is precious. Having more flexible beliefs would mean that one does not limit the scope of ones potential. I imagine that one should therefore encourage others in having more fluid beliefs and one should guard against others when they say reality is fixed.

For example: a man with no legs can win the 100 meters race in the Paralympics.
