Here is something I heard from a surfing coach last week about his philosophy of teaching:
Foundation + Flexibility
Teach the sound fundamentals of surfing (or else you could be limited to 1 minute of Stand Up Paddling before toppling over, like me) and give the flexibility to each student to evolve his own style.
I can imagine a tennis coach adopting this as a mission statement and trademarking "F&F Coaching."
Interestingly, the Surfing Channel program I was watching was showing a pro surf event on the Oahu North Shore, and two ex-surfers who were commentating ended up arguing whether a certain surfer was showing off his own style, or was it just the regular orthodox teaching that he was following!
