Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For Joint Criteria, these are the strongest matches in the current practice library.

Does this sound like the set of challenges you might be facing?

• The second either of us names a solution, the other instantly shoots it down with a counter
• I decide what still needs work purely on vibes
• We keep landing on "let’s each give up half," and we both walk away a little resentful and a little short
• When two things fit together neatly in my head, I treat the whole package as more likely than either piece alone
• I wave through arguments on my side that I’d tear apart in a heartbeat if the other side made them
