Programming

Memorization is just repetition, and you can build successes and reinforce it for yourself by keeping things very, very small. If even a "simple number guessing game" is too complicated for you to remember at this point, that's not a mark of shame, it might sound simple but one of most important things you can learn as a programmer is that a lot of things that seem or feel simple really aren't. There's sometimes a lot of hidden complexity, and your brain needs to form the internal tools it needs to unpack and untangle that complexity. Eventually you'll develop the skills you need to see the specific issues making it more complex, but for now, all you can do is simplify. If there's a part you're not remembering how to do, discard it. Make it a sidequest. Iterate on one feature at a time, test it and see if it works the way you expect. Refine, and you'll learn a little bit from each refinement. Keep doing little refinements and you'll start learning stuff more permanently. It's like any skill, you have to practice.

If you read through a foreign language dictionary page by page, of course you're not going to remember all the words. It's huge. It's overwhelming. Our brains can't learn that much in a single pass. It's all about doing little bits at a time. The absolute minimum required to get off the ground. Gradually, not overnight, you'll learn it all.

There's a reason the stereotypical "first program" is:

print("Hello world")

It's actually a good starting point. It's all you need to get started, plus the workflow you need to compile/run it, which shouldn't be changing a lot once you've got it established. Other than that, you can build tiny baby steps on top of that. How do you print "Hello again" after "Hello world"? Does it print on the same line or does it print on the next line? Try it out and find out. Learn what it does. Play with it. What's next? How do you let the user type something? Maybe you need to look for some examples. Try them. Not just the first one that works, try them all. See if they do anything differently. Don't copy and paste huge complicated messes of code blocks if you don't understand them, because you're getting back into the "reading the dictionary" problem, but a line here or there is something you can start to pick apart and understand what it's doing as you go. Use your programs to explore and understand what the program is doing, not to create a "finished product". Nothing's ever really "finished" except by accident when at some point in the distant future you realize you haven't needed to modify it in ages. Otherwise, programs are things you change as you go, and you learn something each time you change them.
