Dear Chevra,
We need to remember that, coming out of Yom Kippur, we all have a clean slate. Just for the moment, I suggest putting any long term goals on the back burner, and sticking with two short-term goals:
1.) Staying clean, one day at a time, and
2.) Staying clean until Sukkos.
It's less than four days away, but staying clean until Sukkos will allow us all, b'Ezras Hashem, to have the most wonderful Simchas Yom Tov that we've had in a long time, and will give us success to build on both during and after the Yomim Tovim.
Of course, once Sukkos begins, the short term goal should be (besides, of course, for one day at a time) to stay clean during the entire Yomim Tovim. Once Yom Tov is over, the short term goal should be (besides, of course, for one day at a time) to stay clean until Rosh Chodesh Cheshvan. You get the picture! But forget about these longer term goals, just for the moment, and do what it takes to make it until Sukkos!
Just to clarify: Don't completely forget about longer term goals, such as 90 days, but concentrating on these short term goals can lead to success in the long term goals as well.
