"I can never see a point when I will be satisfied with what I have," said the 30-year-old.
"I will just be annoyed, thinking I want extra. It would grate with me if I felt I was missing out on a trophy."
Ferdinand uses the example of Edwin van der Sar to illustrate his point.
Although the veteran Dutchman has won everything the club game has to offer and amassed a record number of caps for his country, appearing in three World Cups, he had no hesitation in agreeing a one-year contract extension with the Red Devils, feeling there are trophies still to be won.
"The simple reason Edwin is staying for another year is that he can win things," said Ferdinand.
"He wouldn't want to retire knowing his body was capable of going on, that Manchester United were still winning trophies and he was missing out."
