Scott Ginsberg has a post (see link below) that has so many great quotes that you just need to check it out !
HELLO, my name is BLOG: Life isn't about finding yourself, it's about creating yourself
After reading Scott's post, I would summarize it like this ...
Learn from what you did in 2005. What worked? What didn't? What did you try for the first time? What did you intend to try, but did not?
Once you learned.... How are you going to apply your learning in 2006? Now is the time to make plans and MAKE YOUR DREAMS HAPPEN !
