Colin Farrell
There was a time when Farrell was one of Hollywood’s most notorious bad boys. The Irishman was a heavy drinker and consumed drugs like a child in a candy shop. But he did the bravest thing he could and acknowledged his problem. Farrell checked into a rehab facility and began mindfulness therapy.

He later opened up about the experience. “I’d gotten out of control. For years I could indulge in certain things,” Farrell told David Letterman (via Landmark Recovery). “I had quite a high tolerance for various drugs for years, I thought. It accumulated to the point where I couldn’t put my foot on the brake anymore.” Clearly, he needed help, so it’s good he did what was the best thing for his career and life.
