1) Go outside more - I've always been an introverted bookworm (are there extroverted ones, I wonder?), but my kids are very active and experiencial. Sometimes the only place I can handle their energy is in the great outdoors.
2) Appreciate my squishy parts - Being a mom has changed things about my body in ways that make me sigh, but they fight over who gets to put their head on my flabby arms and jiggly belly. They love me, wiggles and all.
3) Laugh more - most things could be worse and probably have been, I'm just glad my last two kids are still by my side.
