‘Humble’ Serena Williams forgets her grand slam achievements

Serena Williams says she is a humble person who sometimes forgets all she has achieved, crediting hard work and a calm persona for her sensational career.

The American, 35, widely considered one of the best athletes in any sport, is on the cusp of beating Steffi Graf to claim an Open-era record 23rd grand slam title.

It has taken her 20 years to get to this point, with few players being at the top for so long.

As she works to claim a seventh Australian Open title in Melbourne, a bubbly Williams, who recently got engaged, said it was easy to forget how far she has come.

“I try to be so humble that I forget I have accomplished so much,” she said, explaining that hard work was key to her success.

“I’ve worked all my life. I worked so many years. I work hard,” she said.
