Choosing the Right Challenge

When selecting a challenge, prioritize understanding over difficulty—it’s better to fully grasp an easier problem than to struggle with an overwhelming one. Consider the computational requirements, as we are limited to laptops. Avoid challenges that demand extensive GPU power, such as large-scale image processing, and focus on problems that can be efficiently tackled with available resources.
