Fresh off her fifth Wimbledon triumph, Williams is eager to defend the Stanford Classic title she won in 2011 that signalled her return after missing nearly a year recovering from serious health problems.
The triumph, which came on the heels of a last-16 loss at that year's Wimbledon, was part of an 18-match win streak that lasted until the US Open final, where she fell to Australian Samantha Stosur.
"This is the place that spurred me on last year," Williams, who missed nearly a year of competition after dealing with a cut foot and blood clot in her the lungs, told Reuters.
"I had a great summer, and that propelled me with getting a lot of confidence and so that really helped, I definitely wanted to come back and try to redo that, but maybe do 19 straight (wins) this time."
Williams not only picked up her 14th Grand Slam singles title at Wimbledon last Saturday, but she also won her 13th Grand Slam doubles title with her older sister, Venus.
She then flew to California on Monday but was so jet lagged that she woke up at 3:30 a.m. on Tuesday and began tweeting.
Williams said her current schedule, which includes competing in the July 27-August 12 London Olympics, is among the most hectic that she has had during her glittering career.
"My goal is to do well here first, and then go from there," said Williams. "I have the Olympics, gosh, I keep forgetting about that, so gotta do [well there], and then I have the US Open, so it's a busy summer and it's halfway through, but it's going so fast."
Williams, 30, became the first woman in her 30s to win Wimbledon since Martina Navratilova won in 1990 at age 33.
She admittedly did not go into 2012 Wimbledon with a lot of confidence as she had been stunned in the first round of the French Open by Virginie Razzano, the only time she had lost in the first round of a Major in 47 attempts.
"I had a very tough week and just regaining my confidence back, playing myself in and then just realizing to let that loss go and recover and do the best that I can," she said.
After suffering a pulmonary embolism in early 2011, Williams thought that she might never play tennis again, but said that being faced with a life or death situation made her stronger and increased her desire for further success.
"The process was tough, just going out there and never giving up and having some tough losses in between, but realizing that I belong on the tennis court more than anywhere else and I do my best on the tennis court," she said.
The top-seeded Williams will open her Stanford Classic title defence on Wednesday against collegiate champion Nicole Gibbs.
