The 24-year-old's meagre return of eight and five in his opening two innings in Australia's five-match ODI series with Sri Lanka have been compounded by his failure to take a wicket in six ODI games for Australia.
"I think every game you play for Australia you feel the pressure to perform," he said.
Big Bash success story Aaron Finch, Usman Khawaja, all-rounder Steve Smith and paceman Ben Cutting were dropped from the 12-man squad following Australia's humbling eight-wicket loss in the second ODI, but Maxwell will make the trip for the third and fourth games of the tied series in Brisbane and Sydney.
And with Moises Henriques returning to the set-up after a three-year exile to provide competition for the all-rounder spot along with mainstays Michael Clarke, David Warner and Matthew Wade, Maxwell is well aware of the fickle nature of his position.
"I still remember my first game only five months ago you know that you could only get one or two chances to play for Australia," he said. "You've just got to take it with both hands and make the most of it."
Khawaja was dropped after making just three in Melbourne, while Finch will return to the Melbourne Renegades for their Big Bash semi-final with the Brisbane Heat following his lone failure with the bat in the second ODI in Adelaide.
The 26-year-old made way for Warner while Maxwell was spared despite two failed innings and no success with the ball, but the all-rounder said Finch's demotion was simply a case of too many quality players being available.
"I'm not really sure (if Finch should have been dropped)," Maxwell said. "He's played very well this domestic season, he's in great knick but I think you look at the guys that are coming back into the side and who do you leave out?"
"Hughesy (Phil Hughes) got a hundred in the first game and he's been good all season and Warner, Wade and Clarke come back into the squad so it's hard to squeeze 15 players into 12."
