"Very much just trying to keep it week-to-week at the moment," Williamson said on Monday. "I haven't had such a long-term injury before but talking to other people that have, the journey is a bit of a long one so if you look too far ahead, it probably can become a little bit daunting.
"Whereas, one week at a time, ticking off those small markers, those little wins that are nice to experience. But also knowing that the journey won't be completely smooth and you have a few setbacks along the way that you have to navigate."
Williamson, 32, who has scored 6554 runs in ODIs at 47.83, said any training he was doing was "elementary" at the moment and he looked forward to getting back in the nets.
"Probably more for sanity and changing things up... just nice to mix up all the gym work and the physio work and rehab specific stuff to spend a bit of time with some of the other guys that are training," he said. "Super keen to get back in the nets, for sure."
The World Cup will be played in India in October and November.
