If we are too quick to admit defeat, we may fail to realize how close we are to being right — Karl Popper
"Difficulty" is the same. Facing a cliff, one might not see a crack in a hundred years, but with an axe, inch by inch, foot by foot, through constant accumulation, leaps will come, and breakthroughs will follow — Hua Luogeng (China)

The development of the general ability for independent thinking and judgment should always come first, not the acquisition of professional knowledge.
