不懂年少轻狂只知胜者为王
[bù dŏng nián shăo qīng kuáng zhĭ zhī shèng zhĕ wéi wáng]
Expressing disillusionment about youthful recklessness (not understanding youth's impulsiveness), this focuses on the belief that only the strong or victors matter. It carries connotations of ambition driven by competition rather than empathy or naivety typical in youth.
