Sometimes backing off and saying "to hell with it, I'm taking a break!" is the only way to salvation.
There's no relaxing with day-in day-out work.
If Nadal is to challenge Djokovic and others he will need to have his motivation and other co-factors all lined up.
Once he does he'll be a force to reckon with but before that he needs to do what he's doing, recharging his batteries.
I have a feeling next year may be a great one, with Djokovic at his level, Murray has had enough of being the doormat, DelPo can regain some form and a few young guns can still disrupt the most carefully laid plans of the top players.
This is what inside tennis lovers know that the ordinary fans overlook, the balance of power and what players do to get an advantage.
