His ambition was to continue his support for his father who he loved very much. Help tutor his close friend Nog in school work so he doesn't fail. Building a subspace transceiver and having an interest in science. Still would've been nice to see that fulfill and had writing as a hobby. Jake never had to be Wesley, who I thought was not a bad character -- a kind of Will Robinson-ish but not bad, but there's more to the character which could've been explored. It didn't have to be Starfleet, it could've been Bajor related or something more. Ok, he's a writer, make something more, make it interesting, but I guess the showrunners' path for Jake was a course of making him completely unlikeable which was the genesis of this thread.
