(I guess money might work as an answer because any waste of a purchased good is a waste of money too. . .) I am most wasteful of produce; the vegs and fruits. I can not begin to count the times I have purchased fruit of any sort or a full head of lettuce thinking I will make this or that with it and then never get around to it. I really need to grow my own garden!
Resources have always been in short supply in my life, so I am frugal with them. I am a firm believer in "waste not, want not". I would also like to think that when it comes to conservation, I am part of the solution, and not part of the problem...Just a thought...
I was going to pick water because I have a leak in the kitchen faucet but when I kept reading down the list, how could I not pick time? I'm sitting here when I could and should be doing other things. Oy!
I'm very good at saving the other things, especially money and electricity. It's water I'm bad at saving. I take 30 min. showers and I wash my car allot. I've got to try harder. :)
I waste my breath a lot on people who are stupid.
