I see your point and it's worth discussing and considering. A field like pure mathematics is pretty academic and there's only so much room at the top. You are judging intelligence and ability in an academic and measurable way. That's not the only way intelligence is used. Can you use your strengths and skills for something that is meaningful to you specifically but wouldn't necessarily be considered an achievement – Can you study, research, understand and talk to doctors enough to help you or a loved one navigate a tough diagnosis or medical issue? Or can you find ways to use your skills to benefit the greater good - like advocacy, writing grants, or tinkering with a solution to an environmental issue?
