Tennis is a fabulous sport to test your sensitivity despite the use of force and sometimes trying circumstances.
Take emotions, for example. The ability to stay serene during a long performance is a trait very sparingly emulated.
Bjorn Borg and Roger Federer are great examples of serenity and a light, well balanced approach. So were Pete Sampras and Ivan Lendl, a bit more serious, but calm non-the-less. Andre Agassi, Steffi Graf, and many more champions also showed a composure far greater than the norm.
In the modern era it is harder to determine the emotional level because of the outward decibel output and demonstrative manner in which a player acts.
Perhaps this is a more enthusiastic approach, perhaps a distraction.
Do what you like, but I counsel you to try serenity sometimes.
