The 38-year-old stopper cited former Fulham goalkeeper Edwin van der Sar as one of the game's inspiring figures. The Manchester United goalkeeper, who is held in high esteem by Schwarzer, recently hung up his gloves at 40 years of age after a remarkable international and club career.
"For me someone like Van der Sar is a great example to follow," Schwarzer told fulhamfc.com. "He's someone I admire a lot for what he achieved in the game and what a model professional he is.
"To see someone of his age gives me inspiration and determination to get somewhere near that. At this moment in time I feel great and I'm working as hard as ever.
"As long as my performances remain good enough to play at this level I will continue to play. I work very hard because the older you get it does get more difficult and you have to adjust yourself with age - the way you live your life, the way you eat and the way you train."
