Welcome to the forum. Hopefully, you'll find an answer here, or come up with an idea, after reading some stuff, of how you can pull it off. Or, to come up w/ an entirely different solution than the one that you were thinking about. I often have those moments of "Wow! Why didn't I think of doing that before?"
I've had a lot of experience w/ faking it. I became so good at it, I think I should have became an actor and worked in the movies.
Yep. I was so good at it -- that even I couldn't tell when I was faking or not. The only one's I seem to have any problems with in regards to faking it, were the judges. Even the cops, probation officers, parole officers, and all the rest were push overs -- in comparison to the judges. But, if I hadn't thought that judges were so smart and so different than the rest of us -- I could have fooled more of them, much more easily.
Just play the part. If you've ever told lies to others -- just tell a few to yourself, like, you don't have to believe what you're telling yourself. There were many times that I sat in AA meetings thinking "Man, I'm not REALLY an alcoholic!" I just had to act like one -- or, I'd start drinking again and screw everything up.
