I don't think I'm necessarily a more productive man because I'm married to Nikki. But almost exactly for that reason I am sure I am a better man and, in fact, a better minister of the gospel, because I'm married to Nikki.
I value her not simply for what she does for me (although I'm happy not to clean the toilet, don't get me wrong). I value her for what she has taught me, how she is so different to me.
