I am a planner by force..LOL Hubby is more the planner but I am the doer.
For meals I have a calendar I write out meals for a few weeks in advance and try to have groceries ready for it so we are ready. I even plan in an eat out night or so esp since we are eating at home more and cooking a lot more now.
When we travel I write out our packing list and then put up a folding table so the kids can lay out their stuff , then check it before we pack. I am a tad OCD when it comes to packing and traveling. We manage to travel even for a week or longer in carry ons. The only time we don't do carry on is when we visit family for Christmas. We usually take a larger suitcase to bring gifts back but even that is getting less now that more my boys are bigger.
For most other things I am pretty laid back, probably more laid back for my husbands liking at times LOL
Laundry/housework is mostly done by the kids now so besides occasional dishes or picking up here and there and my own laundry there isn't much to plan there.
