The single observation I ...

The single observation I would offer for your consideration is that some things are beyond your control. You can lose your health to illness or accident. You can lose your wealth to all manner of unpredictable sources. What are not easily stolen from you without your cooperation are your principles and your values. They are your most important possessions and, if carefully selected and nurtured, will well serve you and your fellow man.
 Neil Armstrong

Quotes from the same author

We would like to give special thanks to all those Americans who built the spacecraft; who did the construction, design, the tests, and put their hearts and all their abilities into those craft. To those people tonight, we give a special thank you, and to all the other people that are listening and watching tonight, God bless you. Good night from Apollo 11.

NASA has been one of the most successful public investments in motivating students to do well and achieve all they can achieve. It's sad that we are turning the programme in a direction where it will reduce the amount of motivation and stimulation it provides to young people.

The single thing which makes any man happiest is the realization that he has worked up to the limits of his ability, his capacity. It's all the better, of course, if this work has made a contribution to knowledge, or toward moving the human race a little farther forward.

For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.

I have been in relatively high-risk businesses all of my adult life. Few of the others, however, had the possibility of direct gains in knowledge which this one had. I have confidence in the equipment, the planning, the training. I suspect that on a risk-gain ratio, this project would compare very, very favorably with those to which I've been accustomed on the past 20 years.
