Damn, i'm like 4 and 5 in shorter than my bros and father. Everyone in my family except me is 6ft5 or taller, even extended and have all been very sucessful.
I have to say, some points make some sense though. I know it was alot easier for me to get jobs than many of my friends when i was younger. And where i worked, i always chilled with people 5+ years older than me rather than people my age.
I don't make money now though, i don't have time to get a "real" job with school.
Short people I know make some $$$$$$$, though, but the logic actually makes some sence to me.
