Ana Ivanovic, who defeated Samantha Stosur in the Australian Open third round and will face Serena Williams in the fourth round, says self-awareness has contributed to her improved results in Grand Slam tournaments.

“I think you learn about yourself through each experience you have,” the 26-year-old Serbian said. “Over past few years I did learn a lot. I made some choices and some mistakes that were not necessarily my decision. Now I really realize that it's about me and it's about my career. I'm more forward in my opinions and the decisions I have to take. I really now am confident more about those decisions, and also the way everything is. I can be more mature player on the court.”
