“Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma – which is living with the results of other people’s thinking. Don’t let the noise of other’s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.” – Steve Jobs
I think this is the toughest thing in life to do. Reminds me a bit of the Desiradata, attributed to Max Ehrmann.

This is a great quote! “…have the courage to follow your heart and intuition.” The word “courage” comes from la couer, meaning heart. Richard the Lion-hearted was known specifically for his courage. Lisa Lionheart was as well, even though the doll never had a second shipment.
