I mean, there you are -- it's late afternoon and you're all played out. But you put a pot of espresso on and soon you've got a mug in your hand. After a sip or two, you have tons of energy -- so much so that you find yourself lashing out at the nearest banker or priest. You're back in the game!
There is no problem so difficult that espresso cannot solve it. Get yourself some espresso and go conquer stuff.
