In Which I Don't Make A New Year's Resolution

I'm contemplating something quite extreme
(At least for me), though I tend to eschew
Those resolution-things (each a pipe-dream
At best; at worst something that, when you fail to do
What they prescribe, you'll feel a failure for
Just acting like yourself). I need to end
A bad behavior, though, but think I'll score
More points in the success column instead
If I just pose a challenge: just how long
Can I go without doing what I ought
To cut back on severely? Just how strong
Can I be on a daily basis? Fraught
With tension this still is, but I do best
When it's a game, or just a tiny test.
