Serena Williams has a simple plan as she enters the twilight of her career.  
One tournament at a time. Oh, and have some fun.

The 31-year-old American enters the season-opening Grand Slam one of the raging hot favourites for the Daphne Akhurst Memorial Trophy arguably in the form of her life.

Williams compiled a 31-1 run from Wimbledon until the season-ending WTA Championships in Istanbul, winning the grass court Grand Slam, the Olympic gold medal and the US Open as well as the Championships titles.

She continued that run by sealing the Brisbane title in her first tournament of 2013 and if successful at Melbourne Park, she will be just the French Open title away from completing her second 'Serena-slam' -- where she holds all four Grand Slam titles at the same time. 
 
Despite her phenomenal run of form, and her superior match record against world number one Victoria Azarenka and number two Maria Sharapova, the powerful American was unsure if she would be able to complete a calendar Grand Slam. 

"That's an incredible goal. It hasn't been done since the '80s," she said in reference to Steffi Graf's 1988 Grand Slam-winning season. "I don't know if I can do it. Maybe someone else can. We'll see,’’ Williams said.

Few would bet against the enigmatic Williams from achieving the result, given how well she was playing over the second half of 2012. 

The real issue, however, is that she has from time to time run hot and cold.   As such, she has adapted a 'take it as comes' attitude.

"My goal is just to do the best I can," she added.   "Like I love playing. I want to be out there on centre court hopefully doing the best I can (and) I set my goals per tournament, go with it from there,’’ Williams said.
