Which sentence from "Icarus and Daedalus" supports the idea that Icarus is reckless?

The sentence that shows that Icarus is reckless is "Who could remember to be careful when he was to fly for the first time?" Reckless is the opposite of careful. When Icarus was told to be careful, he did not even listened to his father as shown in the preceding sentence: "For Icarus, these cautions went in at one ear and out by the other."
