She worked with a coach. Between 1992 and 1993, Diana worked with voice coach Peter Settelen, who was hired to help her develop her public speaking voice ahead of engagements.
Diana has a special connection to Mother Teresa. In 1992, Diana visited Mother Teresa's hospice in Kolkata, India, and met with every one of the 50 patients who were close to death. The two met up again in Rome, London, and New York and developed a personal bond. Mother Teresa died just five days after Diana in September 1997.
Her royal schedule was a busy one. Diana took on numerous charity obligations in the mid-'80s. She carried out 191 official engagements in 1988 and 397 in 1991.
She developed a special interest in charities involving serious illnesses and health-related matters. Diana worked closely with organisations that advocated for mental health, homelessness, leprosy, and AIDS.
She supported animals and the arts. Diana campaigned for animal protection and fighting against the use of landmines in war-torn areas. She was also a patron of the Natural History Museum and the British Red Cross and acted as president of Royal Academy of Music.
