The Liverpool boss had a six-month spell in charge of the Royals in 2009.
Rodgers told the Daily Mail: "I realised I had been giving players too long to deliver.
"I was brought up wanting to develop young talent, and I was loath to cut them off after one or two games.
"I was giving them 10, but before I got any return, I was out of the door. The end point has to be reached quicker now, or someone else comes in."
