Why do some people like to use pencils?

The pencil, the tool of the doodler, represents thought and creativity. Pencils, also children's toys, symbolize spontaneity and childishness. Pencil is also an ephemeral medium for thinkers, planners, draftsmen, architects, engineers, etc. to convey concepts.
Walden author Henry David Thoreau, in addition to being a writer, philosopher, and environmentalist, was an innovator—making some of the best American pencils of his era.
According to the description in "Pencil: A History of Design and Environment" by American popular science writer Henry Podowski, the 19th century was an era of independence and self-study. Manufacturing has attracted many practitioners, so the origin of the invention of the pencil is very obscure, but it is still much simpler than bridges, architectural history, etc. Therefore, "through the pencil's 'introduction', we can go from the simple to the complex, and get a glimpse of the mystery of 'university' such as the history of architecture or engineering", and "from the uncertainty of the origin of the pencil, we can even get the 'ambiguity'. 'Lessons."

Although something as small as a pencil, we do tend to overlook its traces in history. From the girl with a stylus in the frescoes of Pompeii to the manuscripts of Leonardo da Vinci in the Renaissance, from the ancient European brushes, quills to tubular lead balls, to the application of graphite, people are looking forward to the desire to use convenient pen tools promoted the development of this technique.
Emerson said that Thoreau always kept "his diary, and pencils" in his pocket. This detail reflects another reason for Thoreau's passion for high-quality pencil making. The writer is so fond of walking, falling into thoughts at any time, and recording inspirations at any time, if he does not have stationery at hand, but must carry cumbersome ink bottles and quills, he will definitely be troubled.

However, after making a good quality pencil, why did Thoreau give up further research? When friends congratulated him for blazing a trail to riches, he replied, "Why?"
As Thoreau said in Walden, "Most luxuries, most of the so-called comforts of life, are not only unnecessary, but also greatly hinder the progress of mankind."
