There actually is a secret to the good married life. I just came across a reminder of it in this sentence:
"At the cross that relieves my conscience
let me learn lessons of self-denial, forgiveness, and submission."
- from Arthur Bennet's The Valley of Vision, "A Neophyte's Devotion"
To the cross, to the cross!
(Practical note: Reading a Gospel writer's crucifixion account or some excellent cross theology from the Apostle Paul does rather more good than a few seconds' hazy imaginings of 'a hill far away')
