Actress Kate Walsh says success can come to people even late in their careers and that they should not give up. The 44-year-old, who is known for her role as Dr. Addison Montgomery in “Grey’s Anatomy”, says she used to live a tough life herself before a breakthrough in her career, reports contactmusic.com. “Age is just a number. Unless, that is, you live in Hollywood, where there’s the notion that if you haven’t hit it big by your 20s, you may as well hit the road,” Walsh wrote in an article for Harpar Bazaar magazine. “I never dreamed that one day I would land my breakout role at the ripe old age of 36,” she added.
