If you're just starting to learn about computational theory, my biggest piece of advice would be to focus on understanding the basic concepts first, like algorithms, complexity, and the different types of problems (decidable vs. undecidable). These are the building blocks for everything else. It's easy to get lost in the details, but once you grasp these basics, you'll be able to tackle more complex topics down the road. For example, try solving simple algorithm problems and thinking about how they scale with input size. This will give you a practical understanding of concepts like time complexity.
