There are times when you have blind spots. There are times when someone else has been there and done that 300 or more times more than you. There are times when you are not seeing the whole picture. There are times when your good work could be made even better!
It is times like these, you need a coach. Someone to guide you. A person to give you a nudge in the right direction.
Just as the person offering you support is being generous with their guidance you be generous too in your openness to receive. Generous with your attention. Generous with your time. Generous with your openness to learn from those who have trod the path before you.
You never know you might teach the teacher a few beginners tricks also :)
