I want to preface this by saying the question is a little tongue in cheek, I don't personally think that pursuing fame and glory is a good reason at all to be pursuing a career in mathematics. However, I would like to know what people here feel are the sort of traits that mathematicians who produce the caliber of work that would earn a fields medal. Just to provide some background as to why I'm asking this question I'll say a little about myself. Personally I'm still in my last few months of high school, really passionate about mathematics but never any good at the competitions and stuff that get you national recognition like the imo selection exams. Hell I never even made it past the AMC lol, that sort of thing just doesn't interest someone as noncompetitive as me. Despite this I made it into a pretty good university for undergrad and plan on studying math with the intention of getting a PhD afterwards. I'd like to one day produce really great work because I love mathematics but honestly I just wanna spend my life doing what I love.
