don't worry about who will be the target

if you put cheese in a rat trap 

then you don't worry about which of the rats that will get caught 

you check the rat trap when you hear the sound of it closing 

if you fish 

then you don't worry about which of the fish that will bite the bait 

you pull the fishing rod when the bait is bitten 

if you hunt deer 

then you don't worry about which of the deer that you will shoot 

you shoot the deer that is in the killzone
