Michael J. Fox has a big year ahead of him: he'll appear in new episodes of "The Good Wife" this fall and NBC will air a show starring Fox in 2013. His full-time return to television -- along with his "beautiful wife" and "great kids" -- allow him to stay positive while living with Parkinson's, Fox told Ellen DeGeneres on her daytime talk show on Wednesday.

The actor, who has dealt with Parkinson's for 20 years, once worried that audiences would be more aware of his health than his acting if they knew he had the disease, The New York Times reported. Fox left the cast of "Spin City" in 2000 as his symptoms got worse, focusing instead on finding a cure for the neurological disease by raising funds through the Michael J. Fox Foundation. Now he's ready to return to the job that brought him fame in movies such as the "Back To The Future" trilogy and in television ("Family Ties," "Curb Your Enthusiasm," "Scrubs").

"I always say live in the moment, enjoy the day, make the most of what you have," Fox told DeGeneres. "And I said, 'Why don't I just do what I love to do and work?'"

The power of positive thinking is something Fox espouses through his life, his foundation and to his kids. "If you imagine the worst case scenario and it happens, you lived it twice," Fox said.
