Mind your own business

... means take care of your business...
Your purpose ...
Your calling...

If you own or manage a business, and do not actively work to keep the business runnong smoothly and staying profitable, your business will suffer. You, in turn, will suffer whatever consequences that brings.
I am sitting right now in a local business that is undergoing an extensive remodel. The owner says this was necessary to improve their service to their customers. It's working.
He said the restaurant is not usually too busy this day of the week and time of day. It's why he asked us to come in this window.
But the place is hopping.
About 3/4 of the tables are filled with customers and the wait staff is buzzing. There's also a line of customers placing to-go orders at the register.
The owners are taking care of their customers, taking care of their business.
They are minding their business.
And both they and their customers are happy. You can tell from all the smiles across the large room.
Consequences can be good.

Are you minding your own business?
