For sure! I've written a lot about depression too! But I do think a lot of what people otherwise blame on burnout or depression is really this existential hunger to make more positive impact. Finding that highest purpose can change lives!

My depression was due to childhood trauma. No amount of purpose would have changed that. I had to deal with my demons before I could move into the kind of positive space where purpose made any kind of difference.

edit: but yes, now that I have done that work, purpose is good, and what keeps me positive and away from the black dog.
