an immense amount of wealth

close siblings or a loving husband and wife

Professionalism is everything

a starving tiger; something very dangerous

writing that simply follows the rules and has no character

Don't sweat the small stuff

A fisherman

To go up against an unbeatable opponent

To guarantee; To give your seal of approval

All smoke and no fire

a standoff

① The devil's in the details ② A small sacrifice for a greater purpose
