"No matter what I do, I will always have a great career". It's not because she had a baby but because she nearly died having a baby.
The American superstar has been trying to equal the all-time record of Grand Slam singles titles of 24, but twice lost in finals past year.
With Williams serving to take the first set, Strycova managed two break points before the seven-time Wimbledon champion blasted an ace pact Strycova to take Set 1 in just 27 minutes.
"She finished the year number one twice in a row".
Let's remember everything Serena has been through since that last Grand Slam win.
Her claiming to be calm - she attributes this to digging into her memory and recalling how she felt when she beat sister Venus in 2002 for her first Wimbledon title - will reassure her coach Patrick Mouratoglou.
The American was pregnant when she won the most recent of her 23 slams at the 2017 Australian Open. "She has the ability to keep Serena honest". Not getting over-pumped, but at the same time not getting under-wound. And then I returned to the operating room for a procedure that prevents clots from traveling to my lungs.
Williams is now competing at Wimbledon.
Williams came into the tournament after an injury-hit year, where she she was forced to withdraw from three tournaments in a row.
Pregnancy takes an undeniably serious toll on a person's body, even when everything goes smoothly.
"You can try and overpower her which is most likely what will happen, but it's not going to be one-way traffic".
Multiple surgeries after a C-section is a grueling recovery for anyone but particularly for a professional athlete looking to compete among the best again - which Williams remained determined to do. Remember the catsuit for "all the moms out there that had a tough pregnancy"?
A win on Saturday would tie Williams with Margaret Court for the most career Grand Slam singles titles of 24.
"Yeah, I had to get to those finals, looking back, to even be in those two finals a year ago was unbelievable", she said. Barbora Strycova, Williams' opponent on Thursday, will be playing in first major semifinal in her 53rd Grand Slam tournament, while Elina Svitolina will also be making her debut at this stage.
However, Halep broke again immediately and 24-year-old Svitolina gave an indication of her increasing frustration when she netted a simple volley and lashed out, kicking the ball into the net.
"It won't be a match Serena will feel good about - Strycova won't allow Serena to blow her away using one tactic".
The match against Williams is the Czech's first ever Grand Slam singles semifinal and comes just days after she suggested this could be her final appearance at Wimbledon.
Halep cruised into her first championship match at the All England Club with an emphatic 6-1 6-3 defeat of eighth seed Svitolina on Centre Court.
Serena didn't need to return to the court to solidify herself as the GOAT.
But, as she's repeatedly said, she loves the game and the pressure that comes with it.
"I'm trying to be my best version of myself and I fight to win until the very last point because I want to win every match".
