Dame Margot Fonteyn de Arias, DBE, was an English ballerina of the 20th century. She is widely regarded as one of the greatest classical ballet dancers of all time. She spent her entire career as a dancer with the Royal Ballet, eventually being appointed Prima Ballerina Assoluta of the company by HM Queen Elizabeth II.
The one important thing I have learned over the years is the difference between taking one's work seriously and taking one's self seriously. The first is imperative and the second disasterous. -Margot Fonteyn.
