Thoughtful ThursdayJumping off from the Dollars and $ense of Family Building (and by the way, if you haven’t checked out the blog hop yet, please do — and if you want to contribute your own post, even better!)…

One theme I’ve seen come up over and over again in the Dollars and $ense posts is money spent on failed cycles and other efforts that didn’t pan out. Some people seem to accept it as a necessary part of the process. Other people seem to lament the waste. I’ve referred to it in my own post and in a blog post years ago as water-under-the-bridge money, and for the most part that’s how I’ve approached it.

Some people are prudent in their approach to sunk costs, cutting their losses and moving on. Others keep going because of the resources already invested, even when it doesn’t make any sense to keep going.

Eating something that tastes horrible?
Halfway through watching a terrible movie?
Paid thousands of dollars in repairs for your crappy car?
Invested a couple of years in a bad relationship?
Spent tens of thousands of dollars and years of your life trying to have a baby?

With the little things, eating something yucky or watching a bad movie, I’m likely to just finish, even though it would be wiser not to. When it really counts — relationships, big ticket items — I think I’ve been good about cutting my losses. With infertility, though, I was in between: I accepted the losses as water under the bridge, but I couldn’t ever bear to cut my losses and move on. The hard part is that during infertility, you don’t know whether you’re showing perseverance necessary for achieving your goal, or whether you’re succumbing to the sunk cost fallacy and throwing good money after bad. Of all of the awful things about infertility, that part — not knowing if you will ultimately succeed if you just keep going or if everything you put in will ultimately be wasted — is, to me, the very worst.

When there are sunk costs, do you move on or try to stick it out? How does your typical sunk cost approach relate to your family building efforts?
