I think some therapists are better at accepting self improvement as a viable therapy goal, and some need more dramatic problems to keep them entertained. A difficulty with asking them about it is that if you're using insurance, they have to classify it as a problem/diagnosis to get the insurance to pay. It's not hard for them to come up with a problem/diagnosis for most anyone I think, if the person says they want therapy, and you mentioned several things that are normal things to work on in therapy. It just makes it a little trickier to talk about it if you're really looking for self improvement. But I think you can still ask them if they're willing to work with you even if you're not having any crises.
