With a large pink bonnet on my head, I looked around at what would now be my new family and thought, "Well, what a strange custom." Bridal showers were a totally foreign concept to me (I'm British) and my own shower was the first one I had ever been to. One of the games we played involved my new in-laws recounting their best marriage advice. I paid attention, to be sure, but there were other "mistakes" I'm glad I made when I got married, too. That's the thing about well meaning advice: just because it works for one couple, doesn't necessarily mean it will translate to your relationship.
For instance, my mom's best marriage rule (which I have followed successfully for the past 11 years of marriage) is to never go to sleep on an argument and to never sleep separately out of anger. My husband and I have kept this promise to each other and we find it stops arguments from getting out of hand. Instead, we start each day fresh and not carrying quarrels from a previous day.

In fact, she finds when she is tired she can't focus and things get more heated, so she has agreed with her husband to pause arguments and continue the discussion in the morning.
That's precisely why what might be good advice to some can simultaneously be a marriage no-no to others. It's also why I am glad I made these "mistakes" when I first got married:
