Lady Gaga wishes she hadn't been "so hard" on herself in her early days of fame.
The 38-year-old pop star - whose real name is Stefani Joanne Angelina Germanotta - attained massive success in the late 2000s with tracks such as 'Poker Face' and 'Bad Romance' but was perhaps too strict with herself and now thinks that the "most valuable" thing anyone can do for themselves is find their inner-peace.
