There was a trend going around social media last month, maybe you saw it, called No Spend January.

It's a challenge to only spend money on the bare necessities, like groceries and rent, for 31 days.

No takeout, no coffee runs, no shopping sprees.

All in the name of saving a little cash to start off the new year.

And given that more than a third of Americans say they wouldn't be able to cover an unexpected $400 expense, it makes sense why some might want to take up the challenge.

With that in mind, here's the latest installment of our series, My Economy.

Julissa Mercedes in San Diego, California.

This final note on the way out today with a hat tip to Axios.

Homeowners are staying put longer than they have in at least 25 years.

Data provider Adam says home sellers at the end of last year had been in their homes an average of 8.6 years.

That's more than twice the average at the beginning of the century of 4.2 years.

I probably don't have to tell you why, but one big reason?

The golden handcuffs of those ultra-low interest rates we had a few years back.
