We have two minds: an expert mind and a beginner’s mind. In Japanese Buddhism, a beginner's mind is called shoshin. It is a mindset where you maintain an attitude of openness, eagerness, and flexibility. In a beginner's mind, there are no expectations and preconceived ideas. He sees things with an open mind, just like a beginner. You approach every opportunity and experience with openness and non-judgment. As something new that has something new to offer.
In an expert's mind, you judge everything. You have a preconceived idea of everything. You perceive good and bad. You perceive ease and difficulty. Everything has a name and a meaning and a definition.
