You could do the mature thing and do some introspection or go to therapy and develop a sense of self that doesn’t depend on being the smart kid… Or you could just put a bandaid on things by grinding for the PSAT or even the AMC and assuaging your bruised ego with a higher math score than the other 4.0 kids. That should hold you off until you meet a higher scorer.
