Welcome to the family!
So glad you joined our recovery community.
First step is, like you said, day one. Don't drink, one minute, one hour, one day at a time. As you get more sober time, it gets easier to stay sober.
One thing I did to enhance my recovery (and my life) is practice gratitude every day. Every day I find at least one thing I am grateful for. We even have a Gratitude forum here where you can join a thread, or start your own.
I find that when I am grateful for my blessings, my blessings increase. Being grateful also helps me stay sober by focusing on the positive parts of my life.
