She writes down everything that worries her and her greatest fears, then burns the paper

“Anne Hathaway taught me this thing on the set of 'Ocean’s 8.' 

She takes a piece of paper and writes down everything that worries her and her greatest fears. At the end of it, she burns [the paper]. 

I do it a couple times a year. I go out to my backyard, because I’m not trying to set my house on fire, and I get a candle and burn it.”  

~ Mindy Kaling
