Absolutely none. Some years I indulge in them, most years I don't. I'm neurotic enough without widening my sense of responsibility and guilt. Because, let's face it, New Year resolutions often do fail. Far better to sneak up on my nasty habits and clobber them unawares.
And I'm not saying what my nasty habits are.
I hope the new year reveals aspects of wonder in the world and in you. Enjoy.
