Before any vacation, make a packing list, then check each item off as you pack it. This will help you to ensure that you are not forgetting anything vital. I once forgot my toothbrush, and had to run out and buy one when I got there, since then, lists are my go-to.
Most of us have giant to-do lists this time of year, so take it in bite-sized chunks. Take one task a day and do it before dinner. If you have time for more after dinner, more power to you, but at least you’ve gotten one thing checked off.
