Sokka learns that she's pretty good at figuring out solutions to problems. Perhaps after the war is over she could become a mechanist like Teo's father. Or someone who points out the things that people are doing wrong. That seems like something she'd like to do with her life. Most of all she hopes that she gets out of the war alive.
It's funny how Aang is both the reason her life is in danger and the reason why she is alive.
