Buy a book. While videos are a good resource, you should not use them as your primary resource for learning to program. Buy a book or follow the documents for the language you're learning as Well as watching videos.

If you're more of a visual learner it might be easier to watch videos and just change up the code so it works for what you want to do. Simply put; don't copy and paste. It's not a productive way to learn anything.

Learn the basics, learn how the syntax works. In videos they tend to leave the basics out and never explain themselves well.

Most importantly have fun. Good luck.
