Men have scars, women mysteries.
Cersei says this as a remark to Taena's confession that she was not a virgin bride to Lord Merryweather.

Cersei says that same is the case with women, a woman who has secrets appear exciting to men as she has a certain mystery that they can't understand.
Egg, I dreamed that I was old.
Maester Aemon says this as he falls asleep on the deck of the ship sailing them towards Oldtown.

Maester Aemon begins to imagine himself as a young person who has dreamed of his real life of being an old Maester. This also hints at the show's suggestion that the whole story is a dream or a tale narrated by someone.
Every man should lose a battle in his youth, so he does not lose a war when he is old.

Jamie thinks of this while talking to Genna Lannister about her son's death. Genna feels that her son's bones should be interred at Casterly Rock in the Hall of Heroes.

Jaime lies that he was buried next to a stream to placate her as he intended to fool her by giving any random bones, a task easy as bodies were strewn around Westeros due to the recent wars.
