My Comments:

Interestingly, Dr Maxwell Maltz of the Psycho-Cybernetics fame made this astute observation back in the early sixties:

“We are built to conquer environment, solve problems, achieve goals, and we find no real satisfaction or happiness in life without obstacles to conquer and goals to achieve.”

His sentiment had been echoed by Zig Ziglar,

"You were designed for accomplishment, engineered for success, and endowed with the seeds of greatness."!

According to the late Bob Proctor,

"There are six higher-order mental faculties that we have, and how we use them sets the course for our life.”

[They are: 1. Imagination 2. Intuition 3. Memory 4. Reason 5. Perception · 6. Will.]
