I've been keeping a diary since I was about 11. If you don't keep a diary everything washes away. And you can live everything three times: you live it when you live it, you live it when you write it down, and you live it a third time when you re-read it. Though I have to say rereading my diary for publication was a depressing experience. You shouldn't look back.
