A Well-stocked Mind Is Safe From Boredom.

Don't Mess Up The Environment Until You're Quite Sure What You're Doing.

Good Morning, Dr. Chandra. This Is Hal. I Am Ready For My First Lesson.

Some Dangers Are So Spectacular And So Much Beyond Normal Experience That The Mind Refuses To Accept Them As Real, And Watches The Approach Of Doom Without Any Sense Of Apprehension. The Man Who Looks At The Onrushing Tidal Wave, The Descending Avalanche, Or The Spinning Funnel Of The Tornado, Yet Makes No Attempt To Flee, Is Not Necessarily Paralyzed With Fright Or Resigned To An Unavoidable Fate. He May Simply Be Unable To Believe That The Message Of His Eyes Concerns Him Personally. It Is All Happening To Somebody Else.

I Am An Optimist. Anyone Interested In The Future Has To Be Otherwise He Would Simply Shoot Himself.

The Only Way To Define Your Limits Is By Going Beyond Them.
