Mateja started to write short stories at the age of ten and later became a freelance journalist, radio personality, and explorer of the inner worlds. Her life resembles a roller coaster ride full of ups and downs and some pretty wild turns. Among other things, her car was destroyed by tanks and she survived several brushes with death. This contributed to her decision to specialize in spiritual healing, emotional pain, and grief. Mateja graduated in psychology from Arizona State University with the highest distinction, ran an advertising agency for eight years, tried herself in the world of startups, and published several books.
