Don’t be scared to say “I don’t Know”
The smartest people in the world are those who admit that they don’t know.

I Started by looking for a coding language to start with. Then I tried doing some simple things in it, If I got stuck I would look up on how to do it! I might have gt an idea or two! Then I kept going until I felt like I've had gotten it down. Then I tried doing a big project. Then I repeated for other languages

I started learning C with my friend, and then I converted to Python. After that, I learned some HTML and CSS. I also looked into lots of other languages. I mostly learned them off of tutorial websites like w3 schools and also by looking at other people's code and stackoverflow questions.

I learned a lot about hardware/networking a few years back, and messed with Windows' built in FTP server. I learned coding from books and tutorials on the Internet.

codecademy.com is where I started, it was with python and I was learning to do stuff on a raspberry pi

I was very interested in how to build a website, so I started learning HTML, CSS, and JS. Then I started learning Server Side Coding like Node.js, Deno, and Python.

Well, I started off by learning the basic syntax of Python and then moved onto other topics such as recursion which apply more to programming as a whole. I would recommend starting with Python or C++ as a starting language as they are both relatively easy and useful.
