That's an interesting saying.

Those types of nuances and inconsistances are always frustrating but I 
understand it's the nature of working in the real world, rather than 
software. :-)

Oh, that's just about the amount of time it takes before I rotate to the 
next hobby for a while. However, I find that the better I get a things, 
the more I enjoy them and then the rotations get longer for those hobbies. 
I just know that eighty hours is about as much as I can spend just doing 
pure learning before my mind needs a break for a while. It's not really a 
"limit". It's more my "bite size".

I hear ya. There is nearly infinite depth there, no doubt. I just want to 
build up to a basic skill level that gets me functional in a few areas I 
care about.
