uncluttering one day and one thing at a time

Also thinking about the motivation/disheartening aspect - you say you've things packed ready to deliver at the weekend - why not have a mental count of 'things that have gone out' and 'things that will have gone out after delivery' so you can keep positive - or can the things be put in the car now ready to deliver? I find that if they're in the car they're much less likely to end up back in the general mill of things and much more likely to end up at the right destination.
