Wherever you are - be all there.
It's always too early to quit.
Always desire to learn something useful.
Problems are not stop signs, they are guidelines.
I can, therefore I am.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
Leap, and the net will appear.
In wilderness I sense the miracle of life, and behind it our scientific accomplishments fade to trivia.
I have seen the science I worshiped, and the aircraft I loved, destroying the civilization I expected them to serve.
