I just started running in early December 2005, and did my first 5k later that month, so this was a very big goal for me. It was also a lifetime goal.

我从2005年12月初才开始跑步，一个月后第一次跑5千米，因此这对我来说是一个非常巨大的目标，也是我一生的目标。

Every Sim also has a lifetime goal (selected by the player from a variety of choices) like having a big family or ascending to the top of a career path or perhaps just becoming a master fisherman.

每一位Sim都有一个人生目标(这是由玩家在各个不同选择中决定)例如：拥有一个大家族、达到事业巅峰或也许仅仅是成为一位大师级渔夫。
