My household struggles with this too. Part of the issue lies with my husband and father-in-law (who lives with us) both being pack rats and refusing to throw anything away. So I truly feel like I am the only one in a house of 4 (including our 4 year old daughter) who cleans. But I can't let that stand in the way. Obviously if I don't do it no one else will. So, I need to actively perform one act of house cleaning a day until my house is clean and clutter-free!
Today's task for myself: cleaning off the dining room table! It's our main spot of clutter. When we all walk in the door whatever is in our hands gets dumped there.
This is what it looks like right now. I'm getting off this computer and knocking out the table before making another post! Will be back with a pic of it cleaned up later.
