How does working harder solve "rising borrowing costs and oil prices and a rapid depreciation of Korean currency"? Those are all exogenous factors.
For example, your crops are getting attacked by insects. It's exogenous yet if you wake up in the night to come out and kill them, you'll save more crops.
You'll rarely get worse results but it doesn't guarantee better results.
Which is exactly the sort of calculus that leads to people pushing so hard they actually do get worse results. See also: crunch culture.
So if I manually do a task rather an automate it, my results will be better?
