I have taken every imaginable IQ test you can think of. My highest scores were 127 and 136. I can't say I am a succesful person at all.
Meanwhile a cousin of mine who was a plumber, maintenance, and had business cleaning houses has a beautiful house, a plane and got himself a helicopter not too long ago. I can't say he is bright at all; very dumb person, I can't explain his success. Oh by the way the guy can barely spell, let alone speak English correctly.
I guess if you want success, all you need is ambition, my good advice.
