Earlier quoted context omitted.
Actually, that quote was the one sentence I didn't understand. Who's spilling the wine? And why does that buy tranquility? If you could help me that would be great :)
I read it as "instead of getting angry for losing a 20$ note, consider it the price you pay for tranquility". Which maybe works for yourself, but most of my significant others of the past would just start complaining that I lost a 20$ bill.
Most people are annoying: educate them or just put up with them, there is no third option. Also, always remember you are equally annoying to at least some of them.
