Emma Watson rose to global fame at the age of 10 after playing Hermione Granger in the blockbuster Harry Potter film franchise. Starting her acting career at a very young age, she quickly became one of Hollywood's most recognisable child stars. Over the years, the Hollywood actress has successfully moved beyond the wizarding world, building a career as an actress, activist and entrepreneur while carving out her own identity in the entertainment industry.Today, Emma Watson is admired not only for her acting talent but also for her thoughtful approach to life. One of the habits that has helped her stay grounded despite growing up in the spotlight is something surprisingly simple.Emma Watson keeps around 10 different journalsIn a 2013 interview with Rookie Mag, Emma shared that writing has always been an important part of her life. Instead of maintaining just one diary, she revealed that she keeps nearly 10 different journals, each serving a unique purpose.According to the actress, she has separate diaries for dreams, yoga, acting experiences, personal reflections, and even notebooks where she records conversations with people she meets, along with advice they share. She also enjoys creating collage books to document memories and ideas.Watson explained that journaling allows her to organise her thoughts in a private space. She said it gives her the freedom to explore emotions and personal experiences without feeling the need to discuss them publicly. For her, writing things down helps clear her mind and understand herself better.Rather than bottling up feelings, the actress uses her journals to reflect, process emotions and experiment with ideas in a way that feels safe and personal.College helped her find normalcyGrowing up in front of millions of fans came with its own challenges.
