It is not just you...I have this same difficulty, and am wondering if I need to not go out as much, or go out at a different time...
From what I am reading, many people go out way more than we do...The only set activities we have outside the home is church Sunday morning, church Wednesday evening, 4-H meeting once a month, and some church related activities on a Sunday or Saturday once a month...I was going to try to go ice skating once a week...And we also have farm CSA pickup once a week during the growing season (May - Nov) and a dairy farm pickup twice a month on Saturday morning...I do that one alone...
Because we are sharing a car, most errands I run like foodshopping or whatever else I do when my husband is off work...He is off work on Wednesdays and Sundays and works late on Mondays...So most Wednesdays, school does not happen because we are all over the place, trying to run a week's work of errands and appointments...Whatever I can't do on Wednesday I do Monday morning...Not a good way to start the week!
I think the answer for us is to try and get a second car, so I can go out during the aftternoon if I need to, after school but before dinner...Until we get another car, I have to become super organized about our errands, so that they can be done on Wednesday afternoons before dinner, but after school...
School has not been a priority for us in the past, and that is something that will change this year...Until I read WTM I didn't have a strong conviction at all about education...I am grateful for that book and for this forum...For all of you ;)
