Reddit reviews Positive Psychotherapy: Clinician Manual

Have a look at positive psychotherapy:

Clinicians Manual

Learned Optimism
VIA Character strengths

That should be a good start.

It sounds like you are looking for a direction here.

This is a great thing to talk about with your clinical supervisor.

However, if you are willing to take a leap of faith: One thing I have found really helpful for high functioning clients is to take a leaf from positive psychotherapy -- (The book is basically a clinical manual. It's hard to find in libraries, though, unfortunately!) https://www.amazon.com/Positive-Psychotherapy-Clinician-Tayyab-Rashid/dp/0195325389/ref=sr_1_1?keywords=positive+psychotherapy&qid=1568808796&s=gateway&sr=8-1 I actually do a fair number of positive psychotherapy interventions with clients who are struggling a fair bit, as well, and they are usually received quite positively by folks with a pretty significant range of clinical presentations.

I've also found that some clients need to start somewhere more like this and then will move into a more process-oriented place later on.
