Secondly, why "write" a master's thesis? This problem, in my own years of starting a business, has a feeling of being suddenly enlightened after contacting some social practitioners. It's the same three years of coding3, why do master students generally get started faster and improve more than junior college students? Learning ability and working ability are based on comprehensive quality. Take remote collaborative development, which is common in the process of starting a business, as an example: written expression ability is very important for collaborative communication when face-to-face communication is impossible. From my personal experience, most master students can write a written document with clear thinking and accurate expression after guidance. Most pure coding engineers often write a lot, but they don't know what they are talking about, let alone write full of human typos. The process of writing a thesis is actually a very good process of training thinking and writing. "What problem does this paper specifically solve? To what extent have others reached now? What is my whole process of solving these problems? Has my work solved these problems perfectly, and what details can be further improved? " Looking back at the general structure of this paper, will you find that this is actually the general process of solving all problems: finding problems, investigating, making bold assumptions, carefully trying to prove mistakes, summing up problems, and continuing to repeat this process?
