Moving my office

I decided to move our office.
We have one month for preparing the move.
I have been spending one hour every day for the move.
The new office will be one third comparing with our present office space.
We have to throw away many papers and office furniture.
I found many useless papers and needless office furniture.
Though we clean our office every day, there are many spaces where we cannot clean, for example the back of a cabinet.
I am surprised to find very dirty places in our office.
If we don’t move, we will not find such a situation.
I think that an office should be moved every fifteen years.
