Get Rich Quick

The surest way to billions is: military academy -> officer rank -> get funding and support from country's enemies -> coup d'etat -> you own whole country's riches and Rothschild's lick you ass.

Sorry nerds, you science won't earn you money. Only military power makes real money.

he earned a master's degree and a PhD in Islamic studies from the Islamic University of Baghdad

he is gonna make an indecent amount of money out of oil and own a harem.

while you will die poor without a single girlfriend.
