Under added security because of death threats, Federer arrived on a Friday and discussed strategy with ATP player and board representatives till about 1 a.m. He practiced the next morning, spent about 7 hours in meetings with various representatives of the Grand Slams and still attended the player party Saturday night.
On Sunday evening, he hosted three hours of meetings in his hotel room with the Player Council, ATP executive staff, and U.S. Open executives -- all before he struck a match ball.
This guy is a 17 time GS champion, is married, has 2 children, does more advertising than anyone else on tour and still has time to do the work behind the scenes? 
Is there anything he doesn't do well? 
holy smokes. i dont know how he does it.
i think having his family around helps out a lot.
they probably take care of lot of the details concerning his travels. his mom probably takes care of his foundation. dad must manage the money.
but still he is doing a lot of different things which is impressive.
i hardly have enough time left after all my training. and of course my rest and my relaxation during which i try to enjoy my sports with you folks and my friends here.
and i am single with almost zero responsibility.
he has it down to science. every single hour is accounted for well in advance.
