Steve Jobs said it

Steve Jobs, stifteren og idemageren bag Apples mange designsucceser sagde nogle meget kloge ord til de dimitterende Stanford elever i hans graduation tale i 2005. Da jeg så dem gentrykt på Facebook i forbindelse med hans død, blev jeg endnu engang rørt af ordenes sandhed. Her er min favorit.

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. Everthing else is secondary.
– Steve Jobs, 2005
