The Portuguese was sacked after just nine months in charge of the Blues in March 2012 and was appointed as Spurs manager last summer.
However, the former Porto coach feels that the experience has made him learn from his mistakes and improved him professionally.
"The Chelsea experience allowed me to see things in a different way and helped me address the mistakes I made," The Telegraph quotes Villas-Boas as saying.
"That always allows you to develop on a personal and a professional level. There are things I do dramatically different [at Spurs] and things that I do exactly the same because you still have to stay true to your principles."
The 35-year-old also implied that Chelsea's players were reluctant to adapt their game to his instructions during his time at Stamford Bridge.
"It becomes easier when the players are willing to commit to your ideas, they need to be able to take something from learning new things, and also enjoy learning new things that they can use in their game," he said.
Villas-Boas's side travel to his former team on Wednesday.
