I love Gendlin's Focusing and the way that it opens up, confirms and supports my own, experiential knowing. I have a lot to learn still, even though I've been doing this for more than a decade, and I do this by teaching, reading, attending workshops with other Focusing Teachers and offering Focusing to clients.
An important quality for me to keep honing is the sense of just being a person with the other person. Focusing allows me that in broader and deeper ways than other methods I have come across, because it can be so immediate and allows complexity rather than narrowing of understanding.
I have done the initial training three (and a half) times, assisted Ann Weiser Cornell and Barbara McGavin with their work, I'm reading A Process Model with Rob Parker and Neil Dunaetz, and I have followed Lynn Preston's reading groups, conducted a Changes Group and read Gendlin with several informal reading groups.
The philosophical part excites and challenges me, and gives a depth to my courses and to my client work, I think.
