My lectures, based on Islamic teachings, were on various subjects. Some of the titles were, 'The Intoxication of Life,' 'The Purpose of Life,' 'The Real Cause of Man's Distress,' 'The Journey to the Goal in Life,' and, one of my favorites, 'The Heart of Man.'

So my message is in whichever realm, be it going into space or going into the deep sea, you have to balance the yin and yang of caution and boldness, risk aversion and risk taking, fear and fearlessness.

Hope is not a strategy. Fear is not an option.
