A great story taken from The Art of the Start:
Albert Einstein was on a train. He couldn’t find his ticket after searching through his all his pockets and bags. The conductor approached him and said “Dr. Einstein, everyone knows who you are; I’m sure that Princeton can afford to buy you another ticket.”
To which Einstein replied “I’m not worried about the money, I need to find the ticket to figure out where I am going!”
And a great question – have you got your “train ticket” – do you know where you are going?
