It was amazing watching Tommy Haas and Youzhny at the US Open with elegant slices and backhands, and every once in awhile a drop shot to make the point.  They are completely dedicated to trying to be the best athlete on the tour.  100 percent commitment and dedication.  I guess when you love something, there is no debate you Just Do It!  For me, I view commitment as keeping my partner’s safety, needs and desires equal, if not above, mine. Granted this level of commitment requires the right person, the feeling of security and requited connection, but when it exists there is no other feeling like it. Complete selflessness.
