Zoe Saldana suffered from ADD as a teenager.
The 34-year-old actress was dragged to a ballet lesson by her mother following the passing of her father - who died in a car crash when Zoe was just nine - and it was there she learnt to calm herself from the symptoms of Attention Deficit Disorder (ADD).
She said: ''Had my mum not had the intuitive wisdom to put me in ballet I think she would have eventually opted to concede to the medication the doctors were suggesting.
''I was ADD. I was suffering. I couldn't hold a thought. But there was something about the piano, the barre, your breath ... and I became the most quiet, just f***ing lethal little machine with ballet.
''Then for the next ten years, I was dancing. It gave me so much peace, it centered me.''
The 'Star Trek: Into Darkness' actress spent time at a prestigious boarding school in the Dominican Republic - where she moved with her siblings and mother from New York after her father's death - where she learnt to make the most of her basic surroundings.
She added to InStyle magazine: ''You learn to be very creative when you have very little. You outgrow your inner intimidation of things. I got tired of accepting the bullying of all the little rich kids when I was growing up.''
