Of all the things I've lost in my life, I miss my mind the most ........
I agree. . . "..I miss my mind the most. . " as I age.
What I also miss is the quickness -OF MY MIND- when analyzing problems. But 'I believe' that has occurred because I have so much more 'retained knowledge' it takes longer to process and sort out the irrelevant. . . . . . . at least that's MY story.
Your quote reminds me of the old tried and true method we used for resolving complicated problems with computers.
Start off with K-iss I-t S-imple S-upid. Usually that didn't work. . . but you never know.
If that didn't get it fixed, run all diagnostics, use all available test equipment to narrow down the problem area, analyze the results in detail and draw a circle around the area in the schematics where the problem obviously was.
If that didn't work to correct the problem, draw a bigger circle.
(I know it's an oldie)
I have seen so many problems that did not' make sense' that I never tell someone (OK . . . maybe sometimes) they don't know what they are talking about with the 'problem' or the 'resolution'. But always listen to both as they may come in handy.
