Swiss tennis great Roger Federer has hailed wife Mirka for encouraging him to always do his best.  

He told Caminada magazine recently about how Mirka is the most important person in his personal and professional life.  “When I got engaged to Mirka, I  didn’t have any headlines on the board. Our life together is intense and exciting. We like to joke. We have given birth to four children and we are doing everything possible to ensure a bright future for them,” Federer said.
