Math smarts are not the most important thing. Basic reasoning skills are vital (even if they are based on heuristics that are sometimes wrong), management skills are extremely important, intelligence augmentation skills are a must, touchtyping is very useful, etc.
Overall you should think not in terms of competitiveness (whether you are smarter than everybody else), but in terms of co-operation (how you can complement others, how they can contribute their skills to complement yours).
And for the record, I don't think you are the smartest person I know (although you are very smart). I suspect that I may have a better skillset than you do. :)
