A lot of my clients are looking for that one place where they can put their to-do lists of random meetings they have all day. Even if they have a journal, they somehow need one place to put all the information and then they can transport (that info) and figure out what they need to do with it at the end of the day.
I bought these a couple months ago. They were referred to me by a client of mine: They are easy, 3 x 5 to-do list cards in which you (record) your to-dos, and at the end of the day, you execute them and put them in your calendar, if needed. You can order them on levenger.com. Have a great day and always Think Big!
