Vaccination

Imagine you have a busy workweek ahead, and you're feeling overwhelmed by the number of tasks piling up. Tackling a small, manageable task first can build your confidence and prepare you for bigger challenges. Similarly, a vaccination introduces a mild pathogen to your body, allowing your immune system to "practice" and prepare for more severe infections, just like completing a small task preps you for larger ones. In both cases, small, controlled exposure (to tasks or pathogens) strengthens your ability to handle greater challenges later on.
