I have kept an organizer for over ten years now and would feel lost without mine. The one I currently have is a Day Runner Planner which is a very good brand. I've had this organizer for about three years and is still looks almost new. The material looks like leather but it is not. I have an organizer that zips but you can get those that snap or close with a magnet. I think these organizers are especially good for men because you can't cram everything into your wallet. My planner has a calender, address book, notes, pen holder and card holders. It also has pockets to store things such as your check book, check register, stamps, etc.. When I need to take bills to the postoffice, I will zip them up in my organzer with the top of them sticking out of my organizer. This is just my little reminder to drop the bills off. You can also add accessories such as a new calendar or a calculator. The organizers range from $10-$100. It does not matter if you can the cheaper one or more expensive organizer, these planners will come in handy and help keep things in order.
