"Inefficiency" is the New Way to Go

Going back to the multi-tasking topic.

Since there's not enough time, 24 hours a day, to do every single thing one at a time, we're forced into muti-tasking to meet deadlines.

one at a time method = focused, thorough, efficient in terms of total time consumption on one job; but, as its name implies, only one thing gets done.

multi-task method = focus is divided, may not be thorough, but gives multiple jobs at least some progress in a set amount of time.

I guess they are different types of efficiency.
