Being uncomfortable is the point.
If you do not wish to be uncomfortable, why are you here? In this class, in this gym, in this space?
If you are here to only show what you already know, then you are not going to learn.
Learning requires letting go of what you already know, being vulnerable and opening yourself up to change.
If you see yourself as an expert, you may soon fall into the trap of being stuck in the fixed mindset.
On the contrary, seeing yourself as a student keeps the creative juice and the desire to learn going.
Always be the student.
