Analysis
No transcript or reputable news report from the 2007 "Princess Märtha Louise Show" includes this precise wording. While the princess has expressed similar ideas about authenticity and following one's heart in various interviews, the specific quote cannot be substantiated. The phrasing appears to be a paraphrase or a later attribution rather than a documented statement.
Background
Princess Märtha Louise has been active in self‑development and spiritual topics and has given public talks encouraging personal authenticity. However, many inspirational quotes circulating online are paraphrased or incorrectly attributed without primary source verification. The 2007 television program was not transcribed in detail by major Norwegian media outlets.
Verdict summary
There is no reliable source confirming that Princess Märtha Louise said those exact words in 2007.
