这本书的原理和方法都是从职业运动员的训练衍生出来的，如果你将精力看成是肌肉的话，要想在短时间快速提升，需要对这块肌肉进行四方面的训练：
- stability 稳定性，提高肌肉的耐心
- Mobility 机动性，提高肌肉的柔韧性
- Power 爆发力，提高肌肉的速率
- Strength 力量 ，提高肌肉的绝对力量
同样地，精力也需要进行四方面的训练
- 精力的数量（稳定性）：身体的
- 精力的质量（柔韧性）：情感的
- 精力的集中度 （爆发力) ：思想的、智力的
- 精力的力量 （力量）：精神的，深层的价值观
三大基本原理 + 仪式培养
- 周期性原则：过度使用或调用不足都将使得精力下降，我们必须平衡使用精力，并进行周期性的补充
- 滞后性原则：不要等到身体发出警告的时候再考虑补救措施，当我们口渴的时候，身体已经是缺水状态了，所以应该根据原则一进行补充
- 突破性原则：要想提高精力的承受力，就要先消耗超过正常水平的能量，然后再进行恢复。（看励志的东西只能帮助你恢复精力，但不能并能增强精力）
仪式，其实就是即时习惯，决定自己何时何地做某事，将决策交给情景，从而能够间接地战胜你的情感。
这本书能够帮助我们构建一个基本的精力管理系统，但仅仅只是开始，值得我们用尽全力去实践：
- 身体 Physical：睡眠、锻炼、饮食、水合作用、加强身体各个部分的肌肉
- 情感 Emotional：人际关系、同理心、自我调节、
- 思想 Mental：时间管理、创造力、方法 、 集中
- 精神Spiritual：深层价值观、意义、原则
