step 1) Decide I need better organization of my rack cabinet
step 2) disconnect cables. Scribble partial notes on a piece of paper instead of carefully using labels and a spreadsheet.
step 3) discover that it's 1 in the morning
step 4) decide that "rewiring everything tomorrow will be harder", and go on working though I'm tired and groggy
step 5) make terrible rewiring mistakes. Nothing responds to nothing else.
step 6) finally give up, go to bed, remain awake worrying how the heck I will be able to rewire everything in the morning.
For really amazing effects, it can also be combined with:
step 0) decide "I'll do it tonight, because my hands are too tired to rehearse" (discover that a screwdriver used for hours hurts hands more than a keyboard)
step 00) mistakenly measure module Xxx, planning to insert it into the only two available free rack spaces, rotate all other modules, finally discover the obvious: module Xxx occupies THREE rack spaces.
step 000) add beer to the above
step 0000) add plane/train travel due at 5 the morning after
This...I do this, with the final result that nothing will make a sound. Cue wailing and nashing of teeth, sleep till noon, get up , sort it out and vow NEVER to indulge in all night rewiring again.......until the next time.
