I often talk to my classes about taking what your learn on the mat off the mat. This has layers of meaning.
1) Discovering a movement pattern that is leading to/feeding an imbalance.
If you pay attention on the mat, you just might discover habitual movement patterns that are preventing you from recovering from an injury, causing an injury, or are creating an imbalance that may in time cause an injury. This information can be used in your outside of class time. Once you know that you externally rotate one foot, you might well spot that rotation in how you walk or how you stand when you are waiting in a line. And you just might be able to make changes to your physical habits that go beyond what you do in class.
2) Discovering an approach to your practice that may be reflected in other areas of your life.
Do you push hard through pain? Do you constantly readjust your pose? Do you move gradually toward a challenging pose? Do you poo-poo "gentler" work? Do you compare yourself to others? How much do you want to bet that you do that in other aspects of your life? (I personally wouldn't bet against that if I were you.) It's simple: If you are busy watching what everyone else is doing on the mat, you are probably doing the same in other spheres of your life. If you are pushing past your physical limits on the mat, overriding pain warnings, you probably take on too much and neglect your health off the mat as well. It is worth noting your approach in class and seeing where that same approach is showing up in the other arenas.
3) Cultivating self-awareness of one kind fosters self-awareness of other kinds
As you become more honest with yourself on the mat, don't be surprised if that spills over into your entire life. I'm not saying practicing yoga/alignment/movement will solve all your problems. It won't. But becoming clear about a fear you have or a catching a limiting way of talking about yourself can give you opportunities to change what no longer serves you on and off the mat.
Changing what no longer serves you.
That's the whole point of getting on the mat, isn't it?
Deep, and not so deep, thoughts on bodies, movement, yoga, art, shoes, parenting, dogs. You know, life.
