I think he certainly enjoyed the results of his commitment and continues to enjoy the fruits of his labor/sacrifices. I think the point being made is that he wasn't a metro-sexual like Rogi who enjoys flitting about the globe and taking it all in. Fed seems more open to the total experience where as Pete seemed to be more single-minded about it. Both have achieved amazing results using the approach best suited for their character.
Interesting point about the lack of recognition Shankman.
Despite hooking up with The A Train (Agassi) for a few TV ads, the media, and I think tennis fans in general never gave Pete the respect he deserved (and perhaps craved). Imagine being Sampras and seeing all the attention lavished on a young Agassi!!! I'm sure that would stick in my craw for a long time. Perhaps that helped to motivate Sampras to dominate Aggassi in their rivalry? To this day, Pete still gets short shrift from media and tennis fans alike. How many times have you heard someone say something like 'yeah, Sampras was good, but all he did was serve and volley and it was easy for him'. This usually coming from some fellow hacker who randomly sprays serves inconsistently around the box and only goes to the net for the coin toss and handshake.
