I thought all diaries were missing something until I came across the time management diary. I can check all my appointments, create a to-do list, include calls and write extra notes to myself, all in one place. Of course, there is always a downside, it’s bulkier than other diaries, so it’s all you can fit in your binder! (Heads up: good excuse to buy another one!) I use this as my home desk diary. The whole family can add their commitments that involve me, as chief taxi driver, housekeeper and slave. I can write a narrative of the day, note any significant events, instructions, etc. The A5 size is great, as it’s just the right size to include everything without taking up too much space. My one disappointment with it, is that I can’t fit meeting notes into it, for reasons previously mentioned. It would be amazing if Filofax could make a binder with bigger rings… However, I buy one of these bad boys every year, and can’t recommend them enough.
