To you, it is a collection of keys (and affinity tags) on a key ring. (Okay, carabiner.)
To me, it represents dozens of man-hours of thought:
One ring or two? Or three? And what diameter? Fob choice? Fob size? What is too heavy? What is too light? What feels good in my hands? What feels so good I'll forget about it? Is that too good? Is that bad? What would be useful? What would be more useful? Is yesterday's 'useful' no longer so? Where to forgo elegance for functionality? What is the nature of elegance, anyway?
The difference between being a baby nerd and a grownup one is that grownup nerds know to enjoy the process or abandon it altogether, because the "goal", perfection, will continue to recede in the distance as you move toward it.
The key ring of my 20's is not the key ring of my 30's is not the key ring of my 40's.
In my 50's? There may not be a key ring at all.
And maybe that is what I am working towards.
If, indeed, any of this is a working towards anything...
