Keep it vague, and you will keep it.
As a person who doesn’t make New Year’s resolutions, I have several ideas as how to keep them. It doesn’t seem to be that complicated, if you set them so they can meet you sort of half way to being resolved. I have given it some thought (about 7 minutes, I get Hulu with commercials, and used that time wisely) and have decided to generously share my wisdom with the world.
