Unless you're getting paid for it, moving is not fun. But there is nothing tedious and stressful that cannot be made more tedious and stressful by not giving yourself enough time to prepare. If you haven't moved in the last year, you are out of practice and your estimation of how much time and effort it will take to do the various things involved in transferring your stuff from where you are to where you will wind up is probably wildly optimistic.
So, what to do.
Some wait until the last week or two to start packing up the closets and bureaus and garage and kitchen and all and wind up exhausted and not done on moving day. Better to take the most pessimistic guess as to how long it might take and add twenty per cent. The worst that could happen is that you will be done a few days early and look foolish to your family and friends. Much better than coping with chaos and a much, much bigger bill on moving day.
