It's hard comparing yourself to others when you don't know everything. Pictures like this one don't show how the kids have meltdowns and temper tantrums or how the parents start fighting because one always feels like s/he's doing the dishes while the other isn't. You CAN'T compare yourself. Not to one moment in time.
When you're feeling insecure about your parenting, or how you're communicating with your spouse, or how you feel you and your (unmarried or childless) friends don't have the same interests anymore, talk to someone. It can be your parent, or your neighbor, or a friend, or a coworker. Just someone who's in a similar situation as you. You'll be surprised at how much you have in common, and you may just help each other through whatever is bothering you both!
I was surprised to find out that some of my co-workers were having (or had in the past) trouble with their spouses. These are people who have it together!, who are always in a good mood, who truly love their family. Now my husband and I aren't bad, but I've noticed we fight more now that we have kids than we did before. So seeing other people go through the same thing and make it out ok, makes me feel good. Not that I want to fight with my spouse and I don't want that for my co-workers. But I'd say that others going through it was a big revelation for me. Like, "It's ok! Fight...make up...be understanding of each other. We got this!"
