使用 only when 结构强调了真正的失败发生的必要条件。
We live in a vibrant world, and therefore, setbacks and hardships are inevitable.
As the saying goes, "A sword's edge is honed by grinding, and plum blossoms' fragrance comes from the bitter cold." In his autobiography, British historian Welsh dedicated five chapters to the theme of "Starting Over." This is because he faced five failures, one of which was so severe it nearly led to total ruin.
We all encounter failure, but the most important cultivation lies in learning how to rise again after a setback.
Some people are crushed by a single failure; others, despite their losses, find the courage to press on.
The most unfortunate people are those who fall into despair or drift aimlessly after facing failure.
Once hit by a setback, they succumb to hopelessness and give up without trying again.
In truth, the "blows" they experience are often just exaggerations of their own imagination; reality is rarely that severe.
A person has truly met their downfall only when they stop struggling and give up everything.
To fall and stand up again, or to refuse to surrender even when beaten, is a victory in defeat.
Humans are fallible, and we may occasionally stray, but as long as we continue to learn and reflect, we will find the strength to rise again. That is how we avoid true failure.
我们生活在一个丰富多彩的世界，因此，挫折与艰难在所难免。
正所谓“宝剑锋从磨砺出，梅花香自苦寒来。”英国史学家威尔士在其自传中，有五章以“重新开始”为题，这是因为他曾遭遇五次失败，其中有一次甚至到了几乎无法挽回的境地。
我们终会遭遇失败，但在挫折之后学会如何东山再起，才是人生最重要的修行。
有些人因一次失败便一蹶不振；而有些人虽遭遇挫折，却能鼓起勇气，砥砺前行。
在失败后陷入沮丧颓废、随波逐流的人，才是最不幸的。
他们一旦受到打击，便会感到绝望并选择放弃，不再尝试。
实际上，他们所谓的“打击”往往只是个人的过度臆想，事实并非如此严重。
只有当一个人放弃了挣扎、选择彻底放弃时，才算真正遭遇了失败。
跌倒后能够重新站起，或者即便被击倒也绝不认输的人，虽败犹荣。
人总会有犯错的时候，但只要我们能不断发现问题并总结经验，终有奋起重生的那一天，那便不算真正的失败。
"Life is precious and living means fighting; we cannot afford to be mediocre."
"Dedication is life, struggle is joy, determination is strength."
"Greatness is built through blood and sweat."
"No one can achieve success without passionately and bravely pursuing it."
"Life is an endless battlefield that has no place for the lazy."
