I like your point about multitasking.
I grew up as a multitasker, always doing at least 2 or 3 things at once.
Since then, I have had to slow down. Now I get so focused on the one thing I am doing, that everything else takes a back seat.
Focusing on one thing at a time though, I do a much better job of it than when I am doing 2 or 3 at once.
