Worlds LONGEST answer: For me it's staying clutter free and clean. We're a family of 6 (soon to be 7) in a 900sq ft basement, 2 bedrooms one bath. We were just able to add a bedroom and office and kitchen which will help, but fitting all our stuff (our last house was 4000 sq ft) is always rough. Finding a place for everything and not letting it get cluttery is huge. It doesn't help that my husband is naturally the most cluttery person EVER, he leaves stuff EVERYWHERE, even if the place they belong is only a foot away. Grrrr! Anyway the biggest challenge is that I despise cleaning. I love laundry, dishes, cooking, baking and playing with my kids, I love doing the taxes, cutting hair, crafting, and sewing. I'm the handyman, I made my own fireplace mantel, fix anything that's broken, love working with tools. And my favorite thing to do is organize, alphabetize, color code, etc... But I hate, hate HATE cleaning (oh I do like sweeping). I like organizing my kids toys and clothes, but putting them away when they are a mess and all over the floor I just can't do it. So we tend to live with lots of clutter, lots of mess, lots of toys on the floor. I either need a maid or less stuff. Maybe both? and of course the biggest solution is if I could get the new bedroom we just inherited finished (the walls need to be repaired, the trim needs to go up, it needs carpet and paint!) my husband and I could move rooms, then we could separate the kids (girls room and boys room) and everything would have it's place. Extra space will make a HUGE difference in our lives!
