To-do lists......

It's a bright and sunny day here and I hope it stays that way. I have loads of items to finish today and I will do so!!! I'm having a hard time focusing because there are so many things to do, but I have a clear plan today so I should be fine! I read an article in the paper, I think it was the Guardian, about types of to-do lists and what kind are best. Of course, some people don't use to-do lists, but the article acknowledged this and also said those people are clearly nuts. Ha! I had to laugh at that because I always have a list on the go!!! I also read a piece in one of my newsletters about to-do lists and how to best use them. The newsletter argued that it is much better to have only ONE master list so that you don't lose the list or get confused about which list you're working from, etc. The Guardian article said it's important to have TWO lists - one for long-term-might-never-do-it type things and another for short-term-must-do things. I try to keep my lists in the same booklet (not always successful which means that I end up writing the same list in loads of different booklets/slips of paper). I do write two lists though: jewellery vs non-jewellery!! And sometimes I split the jewellery one into actual jewellery vs related things like display, business cards, boxes, etc. Anyway...I think the main thing I don't do well is write the lists consistently in the same booklet, so I'm going to try to do better with that.
Oh yes, and grocery shopping lists are totally separate but we have a good system for that....the cutlery drawer in the kitchen has a space for some pens and a small pad of paper and when we think of something we need to get, we put it on that pad of paper. Then whoever goes to the grocery store can get what we need and just take one piece of paper off the pad. It works!
Any tips from anyone out there? What's the best way to have lists that help instead of hinder??
