UPDATED TIP! I leave my outside lights on 24/7. I used to, in a different house, have lights that had a little cell that would turn them on at dusk and off at dawn. But the cells would go bad and then some would stay on and some others would continue to do the on/off thing. It was a pain in the neck. And I now live outside Chicago where it is gray a good part of the year (like November to March) and it just kinda helps to keep the gray at bay by keeping the lights on all the time. But I know that I shouldn't. Anyone know of any outside lights with proven cells that won't go bad after just a little while?
Well, I tried to find some sort of timer that I could replace my outside light switch with but I just couldn't make it work with some of the switches because they were three-way switches or had three switches on one switchplate and the timers were of a different size. So I decided to just leave the lights off. I turn them on at night when it gets dark and then turn them off when I go to bed. (Seriously, I don't know how I could have been so lazy before!) And do you know that I saw a $30. difference on my electric bill this month!! Just goes to show that, even for me, sometimes trying to do the right thing isn't hard because of external circumstances as much as internal motivations.

Every morning I use a Swiffer cleaner to dust my hardwood floors. That's 365 cloths I throw away each year. Any suggestions?

I use paper towels to clean off my counters. Years ago people used to use cloths such as Handi-Wipes. Then we were all scared off of these types of cloths because we were told that they can harbor harmful bacteria and their use would spread the germs. Any suggestions?

I buy bottled water. Having moved a lot in the 90's I was tired of having to get used to the different taste of the tap water in each new city. I started off with those big, giant 5 gallon bottles of water with the water coolers, but then as individual bottled water became more accessible I moved on to that. But I'm beginning to rethink that decision. The carbon footprint of making all of those plastic bottles is huge and the energy used to recycle them is also great. So I may go back to the huge 5 gallon guys.
