She says she made a choice while young to never have an alcoholic beverage or do drugs. She says her father is an addict, and together with reading the cautionary tale in the young adult novel "Go Ask Alice", about a 15-year-old drug addict, made an impact on her life in this regard. Another book that shaped Gillian's perspective of life is "No Turn Unstoned" by Diana Rigg, a collection of terrible reviews that undeniably great actors received over the years. It was given to her by an acting teacher after she received a very bad review in a local paper for her initial performance in "A Midsummer Night's Dream." Thanks to this experience, she started to see these performances as an opportunity, a chance to improve instead of a burden.
