For the last several years and culminating in six months in orbit next year, I've been training for my third space flight. This one is almost in a category completely different than the previous two, specifically to live in on the space station for six months, to command a space ship and to fly a new rocket ship.

Trust cannot be commanded; and yet it is also correct that the only one who earns trust is the one who is prepared to grant trust.

For me, being able to engage with the details when necessary, when there's a challenge, when there's a particularly important pivot, yes, you have to do that. But in general, a leader needs to trust their commanders, needs to trust the team they've assembled, to actually execute in the right way.

Well-timed silence is the most commanding expression.

I think that is a better thing than thanksgiving: thanks-living. How is this to be done? By a general cheerfulness of manner, by an obedience to the command of Him by whose mercy we live, by a perpetual, constant delighting of ourselves in the Lord, and by a submission of our desires to His will.

As with all commandments, gratitude is a description of a successful mode of living. The thankful heart opens our eyes to a multitude of blessings that continually surround us.

Triumphant science and technology are only at the threshold of man's command over sources of energy so stupendous that, if used for military purposes, they can wipe out our entire civilization.

Long-term, we must begin to build our internal strengths. It isn't just skills like computer technology. It's the old-fashioned basics of self-reliance, self-motivation, self-reinforcement, self-discipline, self-command.

He was very commanding, and you had to know what you were doing to work for Mr. Rogers. I learned how to ride very quickly with him as my riding teacher.

In Shakespeare, unique individuals repudiate the stereotypes demanded by the structure of the play: Shylock commands our sympathy, Barnardine refuses to be hanged. Individuals trump the category.

Smiles come naturally to me, but I started thinking of them as an art form at my command. I studied all the time. I looked at magazines, I'd practice in front of the mirror and I'd ask photographers about the best angles. I can now pull out a smile at will.

Science knows only one commandment - contribute to science.

With the first commandment, Mohammed tried to imprison common sense. And with the second commandment, the beautiful, romantic side of mankind was enslaved.

The conqueror is regarded with awe; the wise man commands our respect; but it is only the benevolent man that wins our affection.

Wherever I look, I see signs of the commandment to honor one's parents and nowhere of a commandment that calls for the respect of a child.

The only thing I command is respect.

In my book I specifically discussed the structural nature of injustice and offered Nine Touchstones of Goddess ethics as an alternative to the Ten Commandments of Biblical religion.

Religion is the recognition of all our duties as divine commands.

I've spent quality time in the aerospace community, with my service on two presidential commissions, but at heart, I'm an academic. Being an academic means I don't wield power over person, place or thing. I don't command armies; I don't lead labor unions. All I have is the power of thought.

To have command is to have all the power you will ever need. To have all the power you will ever need, is to have the world in the palm of you hand.

Power acquired by violence is only a usurpation, and lasts only as long as the force of him who commands prevails over that of those who obey.

Teaching's hard! You need different skills: positive reinforcement, keeping students from getting bored, commanding their attention in a certain way.

All writers have their own pet commandments.
