I don't have any hard evidence or statistics to support the idea behind today's meme, but I can relate to it and have had conversations with others who relate to it as well. It can certainly be a challenge when learning to revisit code and not understand what you meant. Good documentation, or often any, can help on that front, but it's also part of the learning process. How we structure things in code evolves... hopefully for the better.
If you are new to coding, be it application development, network automation, security, or whatever your project might be, hang in there. Is there a learning curve involved? Yes. However, you will have gained some good skills and experience at the end of the learning process. Hopefully, it will reduce the "what is this code that I wrote" feelings.
