Hi Julez-
First off - GREAT attitude about AA and the steps (esp step 3). You are already miles ahead for only being in a short time. Kudos to you.
It's going to take time and practice to live within the principles of AA. It certainly didn't happen overnight for me and I'm almost done (only step 12 to go) and darn near 1 year sober. Instead, it's been a process and some days I do a lot better than others.
The peace and serenity I receive from living within the AA principles ebbs and flows, ususally has a lot to do with my own participation in my own recovery (basically, how much work I'm putting in), but I'm more consistant for sure now than I was when I first started.
