If you are very good at learning, you'll be proficient enough to hold down a job after about a year of studying. That's assuming you make good choices regarding what topics you pick. I would recommend the following order: 1. Any prog language 2. Docker 3. Git 4. Hosting your code in a docker container through a cloud provider Afterward, specialize in whatever seems interesting. Never pay money for a (((certification))), thats a scam where people get diplomas for reading documentation. Instead, you should make real stuff, and add it to your own portfolio on GitHub. Edit: Also, start using Linux right away. Install Ubuntu on an old windows laptop/desktop, and use that for all your coding stuff. Don't shy away from the terminal.
