I think the attachment statement works best being a part of the sentence concerning Leia choosing diplomacy. Diplomacy is all about getting to know everyone around you on a deeper level. Also, after “But” you should ideally be giving a reason for why Leia isn’t suitable for being a Jedi, rather than simply admitting it was personal preference (which feels more like a cop-out). Who knows, perhaps Luke was partially in favor of Leia stopping the Jedi path because of being with Han and having a son? As we see in Book of Boba, he wants Grogu to completely forgo Mando and his past. But I think we can all agree this isn’t the right way to do things as a Jedi at the end of the day. This edit would give the example of Leia to prove that.

So the lesson in the sequels is finally what it should have been all along: defining yourself by your attachments (Rey Skywalker) is a really good thing, even as a Jedi, but you have to have the strength to let go when the time comes. And to not fall into hatred or anger when they are taken from you (Anakin and the Tuskens). It was actually George’s intention to convey this lesson through Star Wars, I believe. Hopefully Rey’s new Jedi Order differs from Luke’s in this way for her upcoming film. It kinda sucks that in the EU this was precisely the lesson Luke incorporates into his own new Jedi Order, but this is the path Lucasfilm has chosen, so it’s best to just embrace it at this point.
