FARM HOUSE ERRANDS OFC
When I have the four columns, I can list the tasks and chores that need to be completed and check them off as I complete them. If I don't need to run out or leave that day, I just leave my Errands column blank. If I need to run to a neighbors house to drop off eggs or pick up something, I include that on my list. Like I said before I don't have to put feeding animals on my list, but if I need to give wormer or clean out the barn, I do put that on my list. For my OFC column, I count reading and answering emails, working on my blog and other internet activities, as well as paperwork, filing and paying bills. These tasks sometimes get done at odd hours of the day for me, but I make sure to give my self a time limit to stay on track.
