I say ... P-SHAW!! P-TOOEY!
If you couldn't or didn't resolve enough to make changes to your life at any particular point in 2007, what makes you think that just because we hit the first day of the first month of a new year of a man-made time-keeper called the calendar that you will be more committed to a resolution?
It's like being nice and contacting someone only when it's a birthday or holiday, like Christmas ... then ignoring this person the other 364 days of the year. What's the point? There ain't nuthin' wrong with all those other days.
You can't have time back, ever! Not that moment nor this moment ... tomorrow never comes, yesterday becomes memories, our perceptions tainted by our own interpretations of events, thoughts and feelings.
NOW is all we know and have. So use it wisely, my friends ...
This having been said and clarified ...
I wish you all a beautiful and joy-filled in-the-moment 2008!!
