I can't change the direction of the wind, but I can adjust my sails to always reach my destination.

If you fell down yesterday, stand up today.

Our work is the presentation of our capabilities.

We are not permitted to choose the frame of our destiny. But what we put into it is ours.

The world breaks everyone, and afterward, some are strong at the broken places.

Knowledge is an unending adventure at the edge of uncertainty.

Living well is the best revenge.

Know thyself, know thy enemy. A thousand battles, a thousand victories.

All knowledge is precious, whether or not it serves the slightest human use.

If we would have new knowledge, we must get a whole world of new questions.
