I think that the key to figuring out what kind of girl is best suited for you is knowing yourself. You need to know what kind of a person you are from the inside out. You need to know what kind of people you work best with when you work with them. Only once you know yourself sufficiently you will be able to realize what type of a woman will best compliment you. You will really have to look outside of the artificially constructed criteria like job title and earning power on this one. The girl who's right for you might be working anywhere and getting paid anything.
The Persian girls may be telling you to look for a grounded girl because it's in their culture, but unless that type of girl really compliments you their advice is useless.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
