"The five S's of sports training are: stamina, speed, strength, skill, and spirit; but the greatest of these is spirit." Ken Doherty (1905-1996)
What does this quote mean to you? Do you have a strong spirit on the court? Are you committed to the game and your partner no matter what? I have had partners that have helped us win a match through their sheer WILL!!! For me - SPIRIT is the most admirable trait.
No excuses - just do your best - every time!
