Speaking in May, Knight revealed the period around 2022, when England were heavily beaten in an away Ashes then almost suffered an early exit at the 50-over World Cup, was the most difficult time during her spell as captain.
Knight has been skipper since 2016 and had thoughts during the previous 50-over World Cup that it might be her last, but the next one in India is now only about 10 months away.
Knight, who will be 34 next month, said: “That was a thought I had at the time, but the next one comes around quickly.
“I’m not looking too far ahead because we have two massive series in South Africa and Australia. That World Cup is around the corner, but let’s see how we go with these ones.”
England’s tour of South Africa includes three T20s, three one-day internationals and a four-day Test, mirroring the format of the Ashes series in Australia just after Christmas.
Knight does not believe her side have a point to prove in South Africa or Australia following the World Cup showing.
“Setbacks make you more motivated, keep you humble and make you work harder,” she said.
“I wouldn’t say it’s proving a point. It’s about us continually trying to be better, being in positions to be successful and do what we want to do.
“We’re pretty confident that we can continue to evolve as a side and play our best cricket during those big series.”
