"No major changes in the first year" is a common suggestion for newcomers in AA. It means holding off on moving, changing jobs, starting a relationship, etc. It's not a bad suggestion. If these things don't work out -- or even if they do -- change can drive people to drink or use again.
But I didn't take the suggestion. And I'm glad I didn't: Dating in my first year helped me find the love of my life. Now I'm happier than ever, and still sober.
