It is unclear what many days away achieves, except for straining the expense budget and consuming valuable time.

目前还不清楚，除了消耗支出预算和宝贵的时间之外，外出休假几天还达成了什么效果。

And I don't mean “smart” like responsible, although it never hurts to budget your travel expenses or think about building a 401k.

我说的“smart”并不是负责任的意思，尽管把你的旅行费用编入预算或者考虑建立一个401k计划（养老保险制度）从来都没有坏处。
