A couple years ago, my wife was complaining once again about someone using scissors and not bringing them back to their proper storage place. "How can we have 3 pair of scissors and none of them are here when I need to use one?" This didn't bother me but hearing her complain about it did bother me. After a couple attempts to reason, "it isn't that big of deal to track a pair down" or "how often do we really use them?", I decided that abundance was a better solution. I found a 4 pack of decent scissors for about $12.
So for $12 dollars I have never heard that complaint again because even if someone walks off with one and doesn't get it back right away there are several more. So my wife doesn't doesn't experience that frustration and it keeps her from getting fixated on something as insignificant as the location of pair of scissors. And, I have already decided that if it happens again I will buy another pack. They are surprisingly good scissors for $3 each.
I think my broader point was that we as humans are sometimes irrational about certain annoyances in life. And, if I can find a way to spend some money and just solve the issue that is probably a good use of money.
