I'm sure you're quite aware that I would have to jump in here on this one!!
On the days that I don't have a plan... it's because on those days I have procrastination, sloth, and envy.... that someone other than me has what I wanted or felt I deserved... but I wasn't willing to plan and work to have what I wanted!!!
Now Mr. Zip... this is NOT for you... because I heard this way before your birth into the land of the Living Sober!!! (Means... doesn't pertain to you my friend).... and has nothing to do with your post!!! So... don't get nerved up by it!
When I was new in AA... I would hear Oldtimers say, "If you wanna make God laugh... show Him your plans." They were usually the one's who had been around for years... but were restless, irritable, discontented, and real sour-pusses on life. And, when I would hear them say it, I thought they were using it as an self-justified excuse for being miserable and having nothing.... but physical sobriety.
Now... when I think of "If you want to make God laugh, show Him your plans" I interpret it as "That's because the results and outcomes that He gives to those who plan... and work for it... is way better than anything they could have imagined for themselves. So, if He laughs, it's because He's laughing at how they short-changed theirselves in regards to what they thought they could achieve."
"God grant me the willingness and courage to plan and work to have the things that I pray for!"
Procrastination and Sloth are the two stickiest character defects for me... and when I ask God to remove them (daily)... His reply to me is "Then get your damn To Do List for the day done.... or else you'll spend the day in procrastination, sloth, misery and confusion. And, by the end of the day, you'll be worse off than you were when you started it... when you start it without a plan."
The idea of the "Daily To-Do List" and "Short-range and Long-range planning was drilled into me by my sponsor. I used to think "And you think a stupid daily To Do List will help a much more educated and advanced form of Human Being such as me?" (No. I was not dumb enough to say that to my Sponsor... I only did it in my head).
Then, one day... while following the Daily Instructions found in the Big Book, on pages 83-88... I discovered that what my Sponsor was telling me to do... was written down in specific details in the Big Book.... "How to do it" (is what I call it). And, you can sure tell the difference in my Life, when I'm doing it and when I'm not doing it! The results and outcomes are nothing less than amazing!
Oops!

Sorry for sharing too much!
Thanks for letting me hang out here!
