( CNN ) -- The only thing Venus Williams treasures more than winning is a decent nap . Venus Williams knocks Anastasia Pavlyuchenkova out of the Barclays Dubai Tennis Championships on February 17 , 2009 . Just before a match , when other top tennis players might be psyching themselves up for a three-set onslaught , the elder of the Williams sisters can be found somewhere private , snoozing . `` I 'm always sleepy , '' she told CNN in an interview for this month 's edition of `` Revealed . '' `` I 'm literally taking a nap during the first set and the match before me , so I 'm probably the only person that can go to sleep , come out 15 minutes later and start playing . '' Wary of sending the wrong signals to her rivals , the sixth seed confessed to CNN that she prefers to take her naps in private . `` I 'm wondering if my competitor is going to see me here , so I try to act like I 'm not asleep , but I am asleep , or I try to find a place where I can sleep in and no one will see me , '' she laughs . The lightning-fast speed of Venus ' serve is at complete odds with her personality . She is strong , ambitious and determined , but also surprisingly laid-back for someone whose professional career is about playing harder , longer and faster . Watch Venus Williams on `` Revealed . '' » . `` I just always go with the flow , '' she told CNN . `` On the court , that 's when I get most intense . In practice , I scream and yell and threaten to throw my racquet but in the match I 'm not like that at all . '' Her younger sister , world number one Serena , sounds almost envious of Venus ' ability to keep her emotions in check . `` Venus is really , really unusually composed and that 's just her style , '' Serena told CNN . `` On the court she 's always really focused . She always has this quiet tenacity and she never really shows her emotions which I think is good . '' The youngest of five sisters , Serena says she continues to draw inspiration from her closest sibling . Venus is just 15 months older than Serena . She set the marker for success in 2002 when she became the first of the sisters to become world number one . Serena first took the title in July of the same year and reclaimed it earlier this month . `` She 's my bigger sister , she 's my older sister , she 's a role model for me , '' Serena said . `` I 'm always trying to do what she does . If she 's going on the right path then I 'm going on the right path too . If she 's working hard then I want to work hard also . I 'm the little sister who wants to be just like the big sister , '' she added . If they once struggled to find the required ruthlessness to eliminate each other from a competition , it is clearly no longer a problem . Of 18 matches they have contested , each sister has won nine . At the time of writing , there is every chance they will meet again this week in the semi-final of the Barclays Dubai Tennis Championships . They last clashed at the Sony Ericsson Championships in Doha in November 2008 when Venus dispatched Serena in three hard-fought sets before going on to win her first end of season title . Watch Venus take the title . Asked after the match about accusations they do n't play as hard against each other as they would normal rivals , Venus replied , `` You have to play hard against a Williams or you are going home quickly . We try our hardest and I think that everyone knows that by the effort level . '' Their mother , Oracene Price , told CNN she keeps her advice on the subject simple . `` I just tell them to remember they are sisters and how love and how to care for one another is more important than anything , '' she said . `` So , this is just a game and eventually it would be over and you will have to live with each other . So , just go out there and do your best and whoever wins , wins . And whoever loses , better luck next time . '' Having said that , Price admits she keeps her distance from whoever comes out second best , in any match . `` They do n't want to be talked to , they do n't want you telling them anything , they just want to be left alone and that 's what I do , '' she told CNN . There was no need for tip-toeing after the second round of the Barclays Dubai Tennis Championships . Venus made fast work of Russian Anastasia Pavlyuchenkova , beating the 17-year-old 6-0 , 6-1 in less than one hour . Venus told CNN her ambition this year is to topple Serena to become the world number one . `` I think I am in a great position to do that , '' she said .
