Every New Year's Eve, for the past twelve years, I've written a letter to myself to be opened the next New Year's Eve-- which means that I start my night by reading the one I wrote for myself the year before.
In the letters I set goals, make predictions--both meaningful and silly--and generally just shoot the shit with myself. It feels as close to time travel as I ever hope to get.
I like this tradition because so often we tell people "nothing much" when they ask what's been going on lately, and often it really feels like that because you're swept up in the minutia of day to day life. Hearing from yourself a year ago though, really puts into perspective just how much you have accomplished, just how much you have changed. It also keeps you a little more on top of your resolutions when you know that you're going to have to read about them again when you hear from that self that really believed you could do it.
Happy New Year to everyone out there!
