Yes, I am OCD about making lists, especially packing lists. I love having everything very organized down to being obsessive-compulsive about it. I have my basic list in Numbers (similar to Excel, only an Apple product). I update/change it for the specific trip we are planning. I even color code it.
In addition this list, I also have a trailer packing list for every type of racing we do. I know it seems OCD, but it has saved us forgetting things many times. I will continue to embrace the obsessive-compulsive list maker that lives inside. Try it, you might like it. Now, a grocery list…that’s something I need to work on.
