1. If we admit failure too readily, we may not realize that we are very close to being right.

---Karl Popper

2. The same is true for "difficulty". Facing a cliff, you can't see a crack in a hundred years, but with an axe, you can get in inch by inch. Step by step, keep accumulating, leaps will come, and breakthroughs will follow. ---Hua Luogeng (China)

8. Scientific inspiration can never come by waiting.
