When we got engaged, I was told by an older gentleman that women changed every seven years, change with them and remember why you love them. The other things he recommended was whichever one got home first had to allow the other one 15 minutes to relax and get comfortable before they discussed any problems of the day. He had been married for 40+ years at the time; my goal is to do the same.
I sum it up like be ready to grow together and control the drama.
