Your time is limited. So don't waste your time living in someone else's life, falling into the trap of a doctrine, that is, falling into the trap of someone else's thinking. Those whose doctrine you want to live your life, but they did not follow the doctrine of others, their own doctrine. Don't chain your own inner voice to the shackles of others. And most importantly, have the courage to run through your mind and intuition. Either way, they already know what you really want to be. Other than that, everything else is a very minor matter.
When I was young, a wonderful magazine called The Whole Earth Catalog was published; Which was the Bible of our generation. It was brought out by a gentleman named Steward Brand. He brought the magazine to life with his poetry.
Stuart and his team produced many issues of the magazine. In the mid-seventies, when I was just about your age, the last issue of the magazine was published. The last page of that farewell issue had a picture of dawn. Below it was written - Be hungry, be foolish. It was their farewell message. Be hungry, be foolish. And I myself have always tried to adhere to it. Today, as you move beyond the confines of university to enter a larger, newer life, I urge you to do the same.
