该句使用倒装结构强调条件与结果之间的关系。
Life is not always filled with happiness; sometimes, we must traverse the endless dark tunnels of adversity. Life itself may lack inherent meaning, as every existence is an accident. To make life brilliant, fulfilling, and eternal, we must establish our own purpose—a clear direction for our lives. Only by fighting relentlessly for this goal, refusing to compromise or give up, can we progress toward our destination, explore the essence of existence, and eventually reach the summit of life.
Thus, we embark on an uneven journey toward these lofty goals. One might say that ideals are like matchboxes in a dark room; it depends on whether we are fortunate enough to find one and ignite the starlight that guides our way. The higher the goal, the greater the pressure and the more stumbling blocks we encounter, necessitating even greater courage. However, a purposeful adventurer is always superior to an aimless explorer. Regardless of how difficult the victory is, the former experiences a sense of excitement and pride upon achieving their wish, whereas the latter may simply be acting on impulse or surrendering to fate, wandering aimlessly at life's crossroads, lost and sorrowful in the fog.
人生未必处处充满幸福，有时我们必须穿越如无尽隧道般的逆境。生命本身或许并无预设的意义，每个生命皆是偶然。若想让生命变得精彩、充实且永恒，我们需要为自己确立目标，而这个目标便是正确的人生方向。唯有坚持不懈地为目标奋斗，永不妥协，永不放弃，才能在前进的道路上不断探索生命的本质，最终抵达人生的顶峰。
为了实现远大的理想，我们注定要走上一条坎坷不平的道路。可以这么说，理想犹如黑屋中的火柴盒，取决于我们能否有幸寻得它，并点燃照亮前路的光芒。目标越高，压力越大，挫折也就越多，因此更需要无畏的勇气。然而，有目标的冒险者终究胜过漫无目的的探险家。即便胜利来之不易，但在实现愿望的那一刻，收获的是属于自己的激动与自豪；而那些随波逐流、盲目顺从命运的人，却往往在人生的十字路口徘徊，如迷失于云雾之中，终感迷茫与失落。
