I love a good coach. not even just for bbing but in general. a good coach is worth their weight in gold.
from Lee's standpoint - it can be seen as a "cool factor" look at me I do not need a coach since I am so gifted, smart and have rock solid will power vibe I am getting....
when I was jr golfer, I had a swing coach, I have used a prep coach for bbing. when I hit slump with my mortgage business, I hired a mortgage/sales coach.
but again I put a alot of value into coaching regardless of the endeavor and bond/relationship you form with your coach is part of the experience.
disclaimer: I would not pay an online guru
