A few weeks ago, the display went out on my laptop -- it's an old IBM Thinkpad, and the little fluorescent tube that makes the screen light up finally went out on it. Perfectly reasonable, and no big deal -- other than I had to order the part, disassemble the display subassembly, replace said part, and then put everything back together again.
I managed to do this (a task that involved no small number of miniscule screws of various sizes) not only successfully -- I'm using the laptop for this blog entry -- but ended up with the same number of parts as I started out with: I experienced neither a screw shortage, nor any mechanical amplification (having more parts when I finished than when I began).
Damn, I'm good.
And modest, too!
