well i celebrate new years at Samhain, so actual new years doesn't matter to me. you could try a ceremony at midnight where you make a wish, or cast a spell for something in the coming year. [say you want a raise, or good grades]
personally, i don't do resolutions, i decided when i was a kid they were stupid since most people can't go through with them. i keep two jars, one is full of things i want to improve on [could be read a book, meditate, work on art, or loose 5 pounds as some examples] once i complete one, i pull another slip of paper with a new goal. the second jar i start on January 1, whenever i do something i feel is noteworthy [say i lost 5 pounds, finished a picture, or didn't complain about something] i write it down and place it in the jar. on December 31 i empty the jar and look back at all the things i accomplished. don't know if that's for everyone though.
