生活中唯一真正的失败是不忠于自己所知道的最好的东西。
The only real failure in life is not to be true to the best one knows.
天有多高，地有多厚，通过实践才能得知。荀子强调实际行动，而非“坐而论道”。在自强不息的行动中，才能获得真知，发掘自己未知的潜能。
True leadership is measured by how you lift others up, not how high you climb.
The writer must be a free being, even if it costs him everything.
