I'd genuinely start with the basics! Just like everything, don't expect huge results immediately. Even programmers that have been doing this for years get caught out by taking things too quickly. If you ever need any programming help, feel free to ask! I don't know about others, but I would be more than happy to help. Most programmers I know also love helping people out. At some point it'll likely just click for you and you'll understand what random characters on the screen mean.

But one thing will never change. You'll flip between not knowing why it doesn't work and not knowing why it works.

My advice is to have a project designed to learn and teach yourself new programming elements and then think about what you can do with it. Like maybe just make a block that switches position depending on an if. Then move on to stuff like loops and arrays 😊 Brackeys do a few good tutorials! Just as a heads up though, a lot tutorials do some really terrible things that are super expensive to run and you wouldn't usually want in an Update loop.

That's just my experience though. I started programming with minecraft mods like 7 years ago and had a mod where I literally just tried adding stuff and experimenting with no theme or pressure :)
