I can tell you how I did it. You may or may not find something useful in it that can help you with it.
First off -- what you wrote above about the keep it simple problem -- you could have been writing it about me and it would have fit me perfectly.
Secondly -- what you wrote about the keep it simple problem, above -- describes nearly to a tee -- most of the alkies I've known in recovery.
So -- the bad thing is: You've got a problem.
And -- the good thing is: You're not alone!
And -- even better is: I figured out a way to solve the problem for me. I'll share it with you...
1. I needed something simple -- that could help me keep it simple and not complicated.
2. I added "First Things First" to "Keep It Simple."
3. My solution ended up as "Keep it simple and first things first" and "First things first and keep it simple."
Yes... One is a problem I've always had... I've never done well with One's. ALWAYS had to be at least TWO!

So, I took "Keep it Simple" and added "First Things First" which gave me One: "Keep it simple and first things first" And, Two: "First Things First and Keep it Simple."
Doing it that way gave me one answer for all problems and if that didn't work -- I had another answer!
Having one answer that fit all problems -- and another answer -- just in case it didn't fit the problem -- gave me relief! I didn't have to stress out about it. So, that helped me to relax and keep it simple!
Now... how they work together:
1. When I focus on "First Things First"... I'm not concerned with "The NEXT right action to take"... All I've got to do is focus on "the NOW right action."
2. When I focus on the "NOW right action" -- it automatically keeps it simple for me!
WIN with "What's Important Now!" That really does work! Staying in the present -- out of tomorrow and out of yesterday -- out of "the meeting earlier today" or the "meeting later today!"

Just focus on "right now!" And, if you'll do that -- it will be simple, and easier, and a whole lot more relaxed.
When we think a lot -- the increased brain activity creates chemical gases in the brain -- (that's what thoughts are -- chemical gases that we create to have the thought) -- and, we tend to get addicted to "the brain farts."
