B- work vs Overdelivering

Hi Brooke,
Can you please talk a bit more about the distinction between when it’s appropriate to do B- work and when to overdeliver? These seem at odds and I don’t see how B- work can make you stand out from the competition who are sweating it out to earn As. Is the B- guideline for when you’re otherwise stalled (i.e. a B- attempt is better than never delivering)?
I’ve heard you talk about the massive value you offer clients, and would be surprised if you see yourself as a B- coach or SCS as a B- program ..?
Thank you!
