Basically, the HMB is a tool to help you optimize the management of your family and home. What you place inside is totally up to you, the idea is that you have a "command central" that allows you to access contacts, personal information, grocery lists, your budget, and other pertinent info easily.
To be honest I am surprised I didn't start one of these babies looong ago. It is a fabulous way to stay on track. I will link my YT video below. There I take you through my binder and show you the set up I've created.
So tell me, do you have a HMB or something similar? If not, would you consider starting one?
