First you have to find the motivation to do it
Which is hard and more than organizing.
I think doing it with your spirits sky high makes organizing easier and incidentally fun 😛.
Another is learning self-discipline.
(NOT OVERNIGHT).
But little by little acquire it with small actions this that can give stronger step for when the time comes you do it as if you were to clean your teeth or make breakfast.
Because it is a way to improve the order of the house.
Without motivation it is practically useless to tidy up.
