You know the drill, party hearty through December, then on 1 January make those same-old, same-old resolutions: drink less, exercise more, save money, be nice to [that person who I don't really like], cut out timewasters like TV and internet, blah, blah, blah.
This year, I'm making exactly one resolution, and its the same one that served me well last year:
Have More Adventures.
Do things I haven't done before. Go to new places. Make more memories. Live every minute for all that is in it.
