說到個人理財，我們總是想方設法去省更多的錢。家庭預算了包含了我們想象中可以節省的大大小小的開支，或者至少把錢花在該花的地方。肯定會乘坐使用公共交通工具，而不是自己開車。
When it comes to personal finance, we are all looking for ways to save us loads of cash or, at the very least, spent better elsewhere. One of the things you have surely considered is using public transportation rather than your own vehicle.
公共交通更實惠，因為公交車票價遠低於汽油，但這並不是唯一需要考慮的成本。還記得高中學過的經濟學嗎，牢記機會成本的教訓。高中學過的課程，會想起，這些正是當你做出一個選擇時所放棄的東西。儘管並不是用錢來衡量的，但是，這仍是在做財務決定時仍然不得不考慮的事。
It would be easy to assume that public transportation is cheaper, because a bus token is far less expensive than gas, but those are not the only costs to consider. Take a step back to your high school economics class and try to remember the lesson about opportunity costs. These, as you might recall if you were awake for that class, are the things you give up when you choose one option over another option. Although they are not measured in dollars and cents, they still have to be considered whenever you make a financial decision.
