"My mother drew a distinction between achievement and success. She said that achievement is the knowledge that you have studied and worked hard and done the best that is in you. Success is being praised by others. That is nice but not as important or satisfying. Always aim for achievement and forget about success." Helen Hayes
Helen Hayes was a very successful actress and singer, mostly on Broadway. One amongst 12 people who have won an Emmy, a Grammy, an Oscar and a Tony Award and the only person to have won all of those and the Presidential Medal of Freedom. Her career spanned 50 years from the 1920's to the 1970's. She was known as the First Lady of Theater.
I believe Helen Hayes' quote is very meaningful, for if you have done the best that is in you, you have done everything you can do. That is a perfect performance and one should feel very proud and very pleased having done their very best.
