Studying Programming is coming to me but I forget how I solved the problem...

I'm surprised that automatically programming is coming to me. It blows my mind. I could not think of any logic in the past months and now I am able to solve puzzles in programming. But the toughest part is I forget how I solved the problem too quickly.
For example, the blackjack program. I forgot what thinking process I used to solve that problem. How do I avoid this issue?

That's a reason to be adding comments to your code.

In addition to well-commented code, in real-world programming, you will generally start with a written specification for the code, which documents the tasks to be completed and the algorithms that will be used.

That's a reason to be adding comments to your code.

When you write a new program, I recommend putting in a comment block that describes what it is that you are doing. Here's what appears to be a rather extreme example. It may seem like overkill to do this kind of stuff, but You would not BELIEVE how useful this kind of thing has been to me over the years as I have tracked down bugs and made changes. Small comment blocks in front of each section of code repeats what is said in this long header comment. This block shows the complete action of this section of a particular subroutine in what is a very large overall program.

        ' for each thumb
        '   1) if the thumb file in the thumb file folder differs from the one in
        '      the active thumb file directory, copy the one in the thumb folder
        '      over on top of it. If they're the same then do nothing.

        '      of the appropriate JPEG files to it
        '  3b) else if the folder exists, check to see if all JPEG files are
        '      the same and if so, you're done but if not, then copy over any that
        '      are not already there and remove any that shouldn't be there

        '   5) create a <name>.htm file for that wood

        '                entry for each referenced JPEG file

        '      thumbnail into _@02 main page index.htm (USED TO BE more complex
        '      with two smaller index files)
        '

        '
        '   8) if there is a corresponding htm file in "HTML with comments",
        '      then analyze it and the new one and make sure they have exactly
        '      the same set of href's and img src's and if they do, then
        '      copy over the one from "HTML with comments" to replace the new
        '      one but if they don't then copy over the "HTML with comments"
        '      one with an underscore at the front of the name, and do a
        '      debug.print of that name to alert the user.
