该句通过举例结构表达内心信念的具体内容。
In life, many people face mediocrity or failure primarily due to their mindset. When encountering difficulties, they tend to choose the easiest path of retreat, thinking, "I can't do this, I should give up," which inevitably leads them into the abyss of failure. In contrast, successful individuals maintain a positive attitude even in the face of adversity. They hold firm beliefs such as "I can do it!" and "There must be a way." Driven by the spirit of "pushing forward regardless of the circumstances," they actively adjust their mindset, encourage themselves, and exhaust all possibilities to move forward until they achieve success.
Success expert Napoleon Hill once said: Whether a person succeeds or fails depends crucially on their mindset. The difference between successful and unsuccessful people lies in the fact that successful people possess a Positive Mental Attitude (PMA), whereas unsuccessful people suffer from a Negative Mental Attitude (NMA).
Successful individuals use the PMA Golden Rule to govern their lives, consistently using positive thinking, optimism, and successful experiences to control their destiny. On the other hand, unsuccessful people are guided and dominated by past failures and doubts, leading them toward emptiness, pessimism, and ultimate failure. Those who apply PMA to their lives possess an enterprising and optimistic mindset, enabling them to handle life's various difficulties and challenges with a positive outlook.
在生活中，许多人之所以平庸或遭遇失败，核心原因在于心态不佳。每当面对挫折时，他们往往会选择退缩，认为自己无法应对，最终陷入失败的深渊。相比之下，成功者在困难面前始终保持积极的心态。他们深信“我能做到”和“一定有办法”，凭借着“有条件要上，没有条件也要上”的拼搏精神，不断调整自我，寻找对策，勇往直前，最终走向成功。
成功学大师拿破仑·希尔曾指出：一个人的成功与否，关键取决于他的心态。成功者拥有积极的心态（PMA——Positive Mental Attitude），而失败者则受困于消极的心态（NMA——Negative Mental Attitude）。
成功人士通过运用PMA黄金定律来主宰人生，他们始终以积极的思考、乐观的精神和丰富的经验来掌控生活。相反，失败者往往被过去的挫折与疑虑所束缚，陷入悲观与颓废，最终走向彻底的失败。而运用PMA支配人生的人，拥有进取与乐观的心态，能够从容应对生活中的各种困难与挑战。
