We’ve been over this. Until the end of TLJ, she wasn’t trying to be a Jedi at all. She and Luke are very different.
Yes, but what does she want? In TFA she’s waiting for her family, and has to accept they’re not coming back. She is then forced through circumstance to accept this “gift” of the Force, that she has recieved. In TLJ she has apparently joined the Resistance, and seeks out Luke for council. Luke turns out to be a disappointment, and in her search for answers for the situation she’s been more or less forced into, she gets duped by Snoke in believing, that Ben Solo is the answer for her, and the Resistance. She escapes knowing her parents were drunks, and then having learned her past does not define her, she accepts her destiny to be the next Jedi. On the other hand she doesn’t really have any other purpose or relationships, that define her. Her only friend is Finn, a relationship, that wasn’t further developed in TLJ. All her mentors are dead. She has no history, or lineage. Being a Jedi gives meaning to what would otherwise be an empty existence. By the end of TLJ little remains, but to fulfill the destiny, that was chosen for her by the powers that be.
