I love my diary. I have a cheap one from one of the discount shops but it is really good. It has a pink cover to it and has a week to page diary and then lots of pages for notes. It has a pen holder on the cover. It is similar to a filofax but smaller and much cheaper.
I have been debating about not getting a diary next year and just using my phone but I really can't decide. It makes sense as I always have my phone with me. But I do like to be able to look at the week ahead in my diary. Decisions, decisions.
I love my calendar too. I always have a family calendar and I use it religiously and can often be found on a Sunday evening copying things from my diary onto the calendar and vice versa.
Do you have a diary or use your phone?
