Bir musibet bin nasihatten iyidir

One bad experience is worth a thousand warnings

El elden üstündür

A hand is superior to another person’s hand

Said to show that there’s always someone who can do a better job

Battı balık yan gider

A sunken fish goes sideways

It means that the worst-case scenario has already happened (the fish has sunk), so you might as well stop worrying and have some fun
