I write in a diary every day and also write down everything I eat. I have a journal I write in when I have some kind of blinding revelation or insight. My favourite is my humour journal, in which I write everything funny that has happened. I reread it and laugh about things I had forgotten.
When I was a child I wrote in two five year diaries from the ages of 8 to 18. My father started a bonfire in the back yard and made me burn them. It was because I used to mark each page with a special symbol whenever he had hit me. I really resent losing all those memories of my childhood that I had.
