Climbing to the peak of a certain field without a guide is as difficult as trying to find a way out in the vast wilderness on a starless night. This is not only a challenge of knowledge but also a test of mental strength and endurance. First, you lose the compass of efficiency. Every direction requires trial and error, and every trap must be personally experienced. Precious time and energy are wasted on paths that have already been validated by predecessors. Progress is slow and accompanied by a huge sense of frustration. The deeper dilemma lies in the limitations of cognition. You cannot distinguish which are the core essentials, easily getting stuck in superficial knowledge or falling into a self-righteous bottleneck without realizing it. Lacking a mirror that reflects your own shortcomings, it becomes a struggle with self-doubt.

Without the affirmation and guidance of predecessors, every setback may shake your faith. That kind of lonely exploration in the dark not only requires extraordinary insight and resilience but also a bit of luck, in order to accidentally touch the correct door to the peak before being completely swallowed by confusion.
