When my girlfriend and I started grocery shopping together every Saturday, we would buy a lot of bananas.
We each ate one banana with breakfast every morning, with little variation. This meant that we should buy 14 bananas each week.
But for whatever reason, when you hold that many bananas in your hand, it feels a silly. It felt like way too many.
So I would sometimes drop a few. I would put ten bananas in the cart because it felt more right.
Then, on Thursday, we wouldn’t have any bananas left.
I trusted my gut, but sometimes the numbers don’t lie. Having a hunch is good, but you have to know when it’s time to look at the data.
