Beginner’s Mind is a sense of wonder, about skills, places, things, people, and even about ourselves. Practice it in all you do, whether learning Aikido techniques or talking to a friend, and you will find more depth and richness in your experience.
Keeping an open Beginner’s Mind is a good practice both on the mat and out in the world. Whenever you catch yourself thinking “Oh, this again,” pause and take a fresh look. Stay actively engaged with what you are doing. Ask yourself what about this situation could I be missing? What could I see in a different way? What does this teacher have to say that I have not heard from other teachers? What have I been assuming about this person that might not actually be so?
