Kate has been a part of the royal family for almost eight years now and has been steadily forging a path for herself that will be the main area of concern during her life as a senior member of the family. The duchess believes that early intervention, family support, and openness about mental health issues are the keys to happier and healthier people, and so she has been making it her mission to focus on these areas.
Since 2016, Kate, William, and Harry have championed the Heads Together campaign, encouraging people to be open about their mental health issues. In 2017, with the release of a video of the royal trio discussing the Heads Together campaign, it was revealed that Kate is the one who came up with the idea in the first place.
