Tao is the way
Coaching, is one way of learning about yourself. There are many "ways" to come to better understand yourself.
Coaching is just a word, a neuro-linguistic concept of the relationship between one person and another.
To coach is to guide, if you choose coaching you choose to become open
to the idea that you need to be guided in a new direction.
The question should really be "why not" coaching. And the answer to that, you have yourself!
"Coaching is just a word...."
