“Your time is limited,

So don’t wast it living someone else’s life.  Don’t be trapped by dogma- which is lining with the results of other peoples thinking.  Don’t let the noise of others’ 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
