Finally screwed up my courage to try my first O3. Naturally, I thought I was smart enough to "kinda" follow the process as defined. Predictably (in hindsight of course,) it didn't go nearly as well as it could have.
On the bright side, it was awesome! I learned more and connected more in 45 minutes than I had in 12 months.
Moral of the story - one-on-ones are so powerful, I'm (way) better off having done the first one poorly than not doing the first one at all.
PS - Much thanks to all the thoughtful folk who posted in this forum over the past couple of years. I'm not one for the whole "wisdom of the crowds" thing, but there sure seem to be a lot of wise individuals out there.
