To me, Rand is just a little bit lost. She enlists in Starfleet as a Yeoman to try out the whole space thing and see if it's for her, and she can try it out without having to go through the whole commitment of Academy. And she loves it, so she enrolls in Academy, and then she's a science officer, then a code breaker, and then a communications officer, and she jumps around never knowing exactly where she fits. In the end, she realizes that her life was so valuable because she experienced so much.
imagine rand talking with uhura, who swears that she just had a calling to languages
she asks if rand ever had a calling, and rand says no
not to anything in particular but to life in general, and to everything that life included
and thats what made it great
