Its packing time!

Its just a few days before xmas, and the time for our planned move is approaching very fast.I feel so unprepared coz i havent yet started packing.My partner and i have been working late and getting home tired and without psyche to do anything.Take out has been the order of the day but today it hit me that its time we get extra boxes so that we avoid last minute rahed packing.
We are down sizing and im wondering how the hell will all our stuff fit into a one bedroom apartment????????? Seriously i have to de clutter at the same time pack.I read in some website of a few ideas to pack.Here are some.

>Make sure you have packing materials like tape, scissors, boxes, plastic bags for clothes to avoid buying suitcases.
>Go room by room ie kitchen, bathroom, living room, bedrooms and others
>de clutter before putting any items in the boxes i.e maybe box, clutter box & moving away box so that if you think some items are too hard to part with they`ll be in the maybe box until you make up ur mind on either to give them away or not
>Prioritize your packing in the sense that you pack things according to your needs, this will help once you get to your house to un pack slowly and not everything at once.You cant get your house organised in a snap.
>Get rid of all edibles that might get spoilt on your way depending on how far your moving, try take out to lessen you left overs in the fridge.
>Replace everything you removed during your stay in the rental to avoid issues with the land lord.
>Make arrangements with the moving van a week or two before and always have a back up plan in case they aren't reliable service providers.
>Always leave your rental like you found it even if the caretaker will come afterwards to clean collect all garbage and dispose it in the dustbin after all thats why we decluttered in the first place.!@#*^)
