The fascinating thing is that success isn't always correlated with academic achievement. It's true that some people perform poorly on school but achieve enormous financial success. It's as if your success might shine in a certain field where you possess exceptional talent. It may surprise you to learn that some people who you consider to be exceptionally intelligent in school may have financial difficulties because they are risk averse or make poor financial decisions.
To put it briefly, I completely agree with you. Success is more than simply academics, it's about using your abilities to improve the actual world and leaving a lasting impression. Thus, try not to worry too much about your A grades there are other things in life besides test results.
