Married People: what do you wish you did before getting married?

I wish I had flown overseas to see some of the amazing historical sites I've only read about. My husband won't fly (he fears it) and I don't want to spend that kind of money without taking him with me.

I'll probably go someday anyway, but I love him deeply and would prefer to experience the great moments in life with him.

I'm sure that travelling overseas is not half as fabulous as sharing a life of happiness with a soul mate, so it's a dream that does not need to be fulfilled for me.
