New Year's resolutions fail when they aren't engineered to last and direct you for the entire year. If you aren't reflecting on what it did to you and your life on December 31st, 364 days after setting it, then the resolution failed.
Setting any resolution that won't fit this description is dangerous for a couple of reasons: First, it both will be a failure and will teach you failure. Also, it will distract from the resolutions that could have been successful ones.
You should only set one NYR until you have successfully done one for an entire year, because it's incredibly hard and you probably aren't capable of one, let alone more, until you show that you are. After one successful NYR, you've earned the right to try two, the year after that three, and so forth.
