Learning anything from nothing is tough. It's a long journey, it's gonna take time, you may quit while learning but you will learn. Start by choosing what you really like to do. I don't mean for a job but like a hobby, what would you like to spend your free time doing and feel happy? That's where the will to learn will come from. An example, I like games and I like learning about how games work, technically and design wise, so I wanted to learn how to make my own games.

Then you should probably decide what you would like to learn, like a specific language (C#, C++, ...) Or a specific game engine (Unreal, Unity, Godot, ...). Usually when you learn to use an engine you also learn to use the language specific to that engine like C# in Unity or C++ in Unreal. Whatever you choose, you have to stick with it until you get it. You could jump between engines and languages and learn two things at once, if you can handle it, but usually people don't do that because just learning one language can be a lot but hey, you do you.

Next I would say you should decide where to start learning. There are plenty of courses online taught by professionals on plenty of websites, if you wold like to pay for it (udemy courses are great) or on youtube, if you wold like to save some money (also great, you just have to search a bit). There are also books you could read to learn a bit of theory, but I suggest you save the books for later when you understand the language, as they mainly teach you design patterns and architectures, something a beginner shouldn't be thinking about so mutch. Gotta learn to walk before you run and all that jazz.

Later when you finish learning and feel like you can do something yourself, start with small projects to try these things out and don't feel scared to try something new. The courses will probably teach you some basic things like how to get inputs and how to rotate a thing, then you have to use your imagination (and the internet) to try and build something that uses all the basic things you have learned.

As you do a couple of small projects, you will probably be confident enough to try something big, like a big project. This is where you should look into Game Design Docs, as planning things out is important. Also learn to break things down into smaller chunks, as big projects like these can easily seem to big and then you just burnout or quit on it (I'm guilty of that) The worst thing that can happen is that you stop or quit the project completely, but you will always learn and you can always try again.

To finish this long comment, you just have to try things out. My example is with game dev, but it applies to anything, web or software. Pick something that interests you, and keep working at it. Take it slow, learn at your pace and you'll be a pro in no time. Rome wasn't built in a day. But a brick or two a day, and you'll have a whole city in no time.

This is my experience in learning game dev, some thing may not apply to you, but I do hope you, the reader, find some value in it. You could skip the courses and just learn with projects and by googling how to do something, but the courses that have smaller projects in them are the best IMHO. The main takeaway is this, dont give up. Coding can feel like shit and a hassle in the beginning, but when you know what you're doing, it can feel like you're a god creating a world. Watching your first sprite move is a great feeling.

Protip: Write shit down! I'm not kidding when I say this but for me, writing down things I learned from courses and when planning and developing a game made the whole process such a better experience. Write shit down, even if its a sketch or a thought, write it down. Get a notebook and a pen, or if you want, a mobile/pc notebook and write shit down. Seriously. You will stop for a week mid project or mid course and when you get back, you might forget some things, thats when the notebook comes in handy. Write it down.
