You've got to expect things are going to go wrong. And we always need to prepare ourselves for handling the unexpected.

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.

I am, and ever will be, a white-socks, pocket-protector, nerdy engineer.

Good luck, Mr. Gorsky!

People love conspiracy theories.

I'm substantially concerned about the policy directions of the space agency. We have a situation in the U.S. where the White House and Congress are at odds over what the future direction should be. They're sort of playing a game and NASA is the shuttlecock that they're hitting back and forth.

I suspect that even though the various questions are difficult and many, they are not as difficult and many as those we faced when we started the Apollo [space program] in 1961.
