I should mention that when Erin and I first met, I was actually INTJ. Somewhere along the way, that shifted to ENTJ.
As I wrote in my book, I agree it's good to have some similarities for the basis of a good connection, and the differences are there to fuel growth.
If you're too similar, there's no growth. If you're too different, there's no connection.
Similarity-wise, Erin and I are both trekkies and are going to see the new Star Trek movie in IMAX today.
