Naila - don't despair! Flylady says you are never behind. Her philosophy is all about focusing on your achievements instead of despairing about how much you haven't done. If you can manage it, shine your sink today. It feels good just to have a clear area if the rest of the house is messy. As you are new to the Flylady system, you only need to do the babysteps, which I will post here daily. These help you to establish new habits in your daily life so that by the end of this month you will have new, efficient routines established.
Re: zones - Flylady divides the house up into zones and each week we concentrate on a different area. This week we are in zone 1: entrance, front porch and dining room. That means the missions and decluttering take place in this zone. Gradually, as the weeks go by, you are tackling each room in your house.
Forgive me not replying to everyone, by the way, but this thread is just too busy! I am reading everyone's posts, though, and will reply to any specific questions.
As I keep banging on about shiny sinks, I shined mine last night. I even buffed the taps. The rest of the kitchen is a bit of a mess and the hotspot in the corner is now covering a whole kitchen counter, but it does feel good to have a clear patch in the middle of it all.
Am going back to normal routines this morning, in preparation for school tomorrow, so I have dragged myself out of bed and woken the children up (though I think they might both have gone back to sleep again
). My 'to do' list for today is:
Cup of tea done 
Get dressed (not to lace-ups, but will concede to indoor sandals)
Wake children up again
B/fasts
AM routine - unload dishwasher, reload it with b/fast stuff, put a load of washing on, empty kitchen bin, sort recycling, tumbledry and put clothes away
Weekly shop
Kitchen hotspot - 5 mins on this
'Home blessing' - quick tidy and clean of the house (1 hour max)
DC write last of their thank-you letters
School stuff - uniforms, school bags, PE kits, stationary
Ironing - 30 mins
Visit friends this afternoon
What's for dinner? Thai chicken curry from Menu4Mums
Bedtime routine (get DC to bed at decent hour for school tomorrow)
Before-bed routine (lay out clothes, etc)
Bed at decent hour myself and set alarm for next day
If I have time, I'm also going to start taking down the Xmas decorations. Just want to get back to normal now.
Hope everyone has a good day.
