It's great to hear that you have a strong aptitude for mathematics and that you were able to understand concepts like pi and Einstein's theory of relativity relatively quickly. Having a natural talent or affinity for a particular subject can certainly be seen as a gift, and it's something to be proud of.
Understanding complex concepts and being able to solve problems in mathematics and physics are valuable skills that can lead to exciting opportunities in various fields, such as engineering, research, and academia. It's wonderful that you have found joy and fulfillment in these areas.
However, it's also important to remember that learning and understanding concepts is a journey that involves continuous growth and exploration. While having an initial knack for certain topics can be advantageous, it's equally important to nurture and develop those skills through practice, further study, and challenging yourself with new ideas.
Being proud of your accomplishments and abilities is healthy, as long as it doesn't lead to complacency or a closed mindset. Embrace your enthusiasm for learning, continue to expand your knowledge, and remain open to new ideas and perspectives. With dedication and hard work, you can continue to excel and make meaningful contributions in your areas of interest.
