“Aerodynamics is mathematics for those who haven’t learned to do calculus. In my case, too, for one who hasn’t learned to add or multiply, at least the first time.”

You don’t want a million answers as much as you want a few forever questions.

I am subject to that principle, in spirit and in belief of body.

Every person, all the events of your life are there because you have drawn them there. What you choose to do with them is up to you.

Your conscience is the measure of the honesty of your selfishness. Listen to it carefully.

To fly as fast as thought, you must begin by knowing that you have already arrived.

Whatever steps we take, they’re necessary to reach the places we’ve chosen to go.

Study a lifetime and you see different colors from the same jewel.

Your friends will know you better in the first minute you meet than your acquaintances will know you in a thousand years.

The simplest questions are the most profound.

Some choices we live not only once but a thousand times over, remembering them for the rest of our lives.

The mark of your ignorance is the depth of your belief in injustice and tragedy.

The best way to pay for a lovely moment is to enjoy it.

Civilization… wrecks the planet from seafloor to stratosphere.

Can miles truly separate you from friends… If you want to be with someone you love, aren’t you already there?

Don’t be dismayed by good-byes.

If your happiness depends on what somebody else does, I guess you do have a problem.
