I'm not actually going to do the whole writing a letter to my ten year old self, but a flick through some old photos did get me thinking what ten year old Amy would think of how things have turned out. Sure, there's a lot I'd go back and change; like looking after myself and my money more, not taking school or 90% of the people there too seriously, not taking that sick day that lost me a good job and making sure I told my loved ones, especially ones who aren't here any more how much I adore them.
It's a matter of one question really, "would your ten year old self be proud of how things turned out?"
Just food for thought, I guess.
