Started Unserious, Still Unserious ...
... but somewhat serious.
Long ago, I watched "TV Champion" where origami experts folded unimaginably complex models. That memory was buried until my college years, when I wondered about the technique behind it. It brought me to Origami Design Secrets by Robert Lang.
The year of 2020 allowed me to spend time deepening origami pursuit. My earliest origami friend, Ivan Danny, invited me to a Discord server called Origami Dan. My initial design was wack. I thought it looks nice, but others be like "man... idk about that". Actually they were right, my old models look stupid.
Turned out I lacked of ability to tell what makes a model good. So I folded models from "Works of ..." series by Origami House from cover to cover, and somehow, someway, my designs after that grind look less stupid. Slowly I keep coming up with new designs and hone my skill.
No Deeper Meaning, Just Paper Go Brrrrr!
Why do I design and fold? I asked the same question. As suggested above there's no deeper meaning. Origami is simply an outlet to channel creative energy.
Whenever I walk, commute, eat, or shower, I think about random things including origami ideas. Usually it ends with "hmm it would be cool if we can do this...". I would test it and most of the time it turns out to be a bad idea. However in some cases it became a solution applicable to a design subject. I realized that coming up with ideas, testing, refining, and ultimately creating a design is a delightful process. Human is truly at their happiest when they create something.
