I'm not as organized as the HMB (sounds cool though) but I am in love with my momagenda desktop.
I used a filofax literally every day unless camping or traveling from age 17-35. I guess it helped that I didn't take it with me, but the first one lasted 14 years. ha!
Anyway now I have this momagenda thing with the cheesy name, but I jot down anything to remember in it. It has spaces for each kid, for dinner, pages for kids info (school, drs, etc) our info, address, all that. It could be bigger, but it works. I also stock up on small cheap notebooks (hey more enviro friendly than chucking electronic gadgets for calendars) and I am fond of making my daily dippy lists on it so that I don't clutter the beloved momagenda: clean this room today, soak those beans, do this/that,etc. I have my own little desk where I keep it. Oh I also keep a little notebook near the kitchen where I jot down my grocery list as I need items.
I go in cycles and am def. not on top of everything all the time, but I do really try to just keep up with the laundry, daily pick up adn kitchen clean up, and then I do the real cleaning just bit by bit.
I kinda liked flylady too for awhile. I think mentally staying on top of stuff helps (or I'm just partial to lists) and I think forcing myself to take baby step after baby step when behind sloooowly gets me feeling caught up, better, and then the structure feeds itself. I do get behind a lot though.
I was actually just pondering today that running a household is fricking involved, if you ask me. cleaning/laundry/kids activities/bills/budgeting/shopping/organizing it seems simple at times but it really is so much.
