Overall tonnes of reading and articles over internet. Some of them very shallow, some of them quite thoughtful. I am working on a prompt based email sequence to basically invoke some of the thoughts that are targeted at this.

One external resource you can take a look at is Jordan Peterson's Self-authoring program. Otherwise, all it takes is really just 20 minutes with a blank markdown editor and type out how are you feeling today, what is bothering you and any other thoughts that you have :)
