After experiencing much in life, I have gradually changed, making happiness a habit. I discovered that my joy can be infectious. When asked why, I simply say: happiness is a habit. I should live every day happily, learning to forget what should be forgotten and learning to let go. Although I may not satisfy my material needs, I have learned to comfort the emptiness in my soul. Having walked through it all, understanding is enough.
Stillness is both external quietude and internal peace. It is not only a way to cultivate character but also a treasure for regulating the spirit. To see a thousand mountains yet remain calm, to sail through a thousand ships yet remain unruffled. Stillness is to curb impetuousness and achieve a "clear and quiet mind." Lao Tzu's "doing nothing" implies that through stillness, one can discern the essence of all things. Only with a quiet heart can one perceive reality.
An apple tree finally bore fruit. In its first year, it produced ten apples, nine of which were taken away. Frustrated, it refused to grow further. In reality, it could have continued to grow; once it becomes a towering tree, the forces that once hindered it will become insignificant. Growth is the most important thing. For those striving in their careers, consider the wisdom in this parable.

静，既是身外的安宁，也是内心的平静。静不仅能修身养性，更是调节精神的良方。看尽千山而心如止水，历经千帆而波澜不惊。静是为了克制急躁，达到“心清意静”。老子云“清静无为”，即是通过清静去洞察本质。唯有心静，方能感悟真实。
一棵苹果树终于结果了。第一年，它结了十个苹果，其中九个被摘走了。它感到愤愤不平，甚至拒绝继续成长。其实，它完全可以继续生长，待它长成参天大树，曾经的阻碍都会变得微不足道。成长才是最重要的。为事业奔波的你，不妨细品这则寓言。
