I've just erased eleven years worth of emails from my inbox and changed the account name.
It was weird to scroll through a decade of my life clicking "delete," but I feel now oddly like I've finally got clear sinuses and can breathe again after a long time with a cold. For the last few days, I've been unsubscribing and cancelling all my email subscriptions, news alerts and lists and memberships. Last week I closed my work-related Facebook account, and it all feels so good, I'm looking around wondering what else I can delete.
A long time ago, a friend of mine said that she never stored old emails. She would read it and respond and delete. If it was something important enough to keep, she'd file it under "electric bill" or "directions to mum's house" or whatever. I thought this was an odd thing to do at the time, but now I see the sense of it.
If anyone wants to know my new email address, PM me. I'll be blocking the old one as soon as I figure out how.
