Getting to my Third doubt.
I am feeling better. Looser, and some of the old mental traps have sprung leaks. Keeping at this ...

What is belief: I doubt I will ever regain my edge.

Why is this Belief inaccurate?
Edges come from practice and performance. I've been practicing! And I used to perform, and I will again. Since my edge has returned repeatedly when I returned, this isn't a permanent thing. Plus a little uncertainty or stage fright is customary. If I didn't feel that I would be very worried.

Does any evidence exist for the truth of my Belief?
Of course, that's what it's an issue. Could be not a stark, have edge vs don't have edge thing. More likely it a sliding thing, more edge today, less edge tomorrow. Rising level of edge overall.

What is the worst that could happen if I don't get what I think I must have (or do get what I think I mustn't have)?
This is the big deal. I could lose time, money, and peace of mind chasing an edge that might play hard to get. I'd have to accept a less than joyous life, and permanently forgo doing some exciting things I want to accomplish before I die. I'll be sad, as I like to express my skills.

What good things could I make happen if I don't get what I think I must have (or do get what I think I mustn't have)?
I could divert my talents into helping others overcome what I did if I stall before reaching my final goals. Maybe they can. I could use the time freed up to other ends. I've don't this before, and hate it. My prime goals are prime because both the journey and the achieving of them mean something.

Exit to Action: There's something about this mix of annoyance and feelings of being frustrated that actually help me move forward. It sharpens my attention to a focus on getting out of this bind. It's uncomfortable. I'd like to work my way back to optimal functioning and shed this need to feel frustrated—replace it with a feeling of competence.

I think it is interesting that these feeling arise just with new territory, doing or trying to do something I personally want that I've not quite mastered. The question of edge doesn't come up when I'm making a sandwich, or facilitating a meeting.

So be it ... and so it is!
