I'm mostly of the mindset that, I worry about today. I won't drink today. My mind turns deadlines into pressure, and I don't do pressure well. Everyone is different, though.
I do count sober days (day is day 110). I think it's because I'm stubborn as heck and do not want to start over, or worse tell other people I'm needing to start over, so it works for me.
The most important thing, though, is to stop, however you go about it. Congrats on that!
