tl;dr: Anyone with a spare hour a day (e.g., time currently spent doom-scrolling) can learn a new skill like 3D modeling, a language, or touch typing, and doing so pays lifelong dividends. Expect early practice to feel terrible and show no visible progress—improvement happens overnight during sleep—so 30-45 minutes of daily deliberate practice on fundamentals, stopping before you get sloppy, is the way through. Most people quit before reaching the "mediocre intermediate" plateau where the skill actually becomes useful and self-sustaining.
