Serena Williams can hardly be blamed for feeling that way.

The No. 1 women's tennis player in the world offered advice to ailing Tiger Woods, the former No. 1 men's golfer in the world, USA Today Sports' For the Win reported.

And unsurprisingly, Williams talked about trying to see the positive side of not playing.

"For me I say you should just try to enjoy your time off, and when you're feeling better, get back into it, but it's a process that you don't want to rush," Williams said, according to For the Win.

"Everyone needs their time, so personally, I don't get very frustrated. I enjoy it, do other things, learn about different things ... when you've been doing this for 20 years it get really repetitive, so you can use it as a time to reboot so things don't feel as militant."

Williams is scheduled to take on BFF Caroline Wozniacki in the BNP Paribas Showdown in New York early next week, her first match since the Australian Open. She has withdrawn from three tournaments --- the Hopman Cup prior to the Australian Open because of a lingering knee injury, and Dubai and Qatar because of the flu.

For the 34-year-old Williams, the only tournaments that really matter are the Grand Slams. She has 21 Slam titles, one behind Steffi Graf for the modern day record, and three behind Margaret Court for the all-time Slams record.

The other tournaments now are inconsequential to her legacy. If she wins four more Grand Slams, she is sure to be considered in the conversation for the greatest female tennis player ever.

So it's not a big deal for Serena to skip the minor events. Serena's bigger deal is the fact that she has lost her last two Grand Slam finals to lower-ranked opponents that could affect her confidence in Slams moving forward.

If Williams emulates the Tiger Woods of the last two years that lacked confidence because of his injuries, she could announce her retirement sooner or later.
