‘At 21 I have no regrets’: I just got an email from myself, a decade ago

The message, sent through a service that holds emails for the future, offered some sage advice

I just received a mysterious email. Dear Wilfred," it began. You better be a baller by this time. You better have a hot wife and kids. I hope you have a Porsche. If not, I don't know what is wrong with you man."

The 280-word message, which arrived in my inbox this week, on the morning of my 31st birthday, was actually from someone who I knew well: myself, exactly 10 years ago.
