Marriage is a collision of personality & character. The success or failure can be accurately calculated using reliable mathematical models. Culture becomes a distraction that has little to do with success. Success equals endurance with joy.

The key ingredient of all human relationships is power. Assume that the power coefficient between any two human beings is 100. Power is then distributed on the basis of social rules. In marriage just like any voluntary relationship, power is divided according to personality, not culture. The ideal marriage relationship is one where power between the two people adds up to 100. The closer each persons share of power adds up to 100, the more successful their relationship.

Personality determines desire for power. There are 4 basic personalities, I'll list them plus their respective relative desire for power coefficient.
a) choleric - Relative Desire for Power (rdp) 70-90%
b) melancholic - rdp 50-60%
c)sanguine- rdp 40-50%
d) phlegmatic - rdp 20-40%

Its now easy to see which relationship is doomed from the start. Remember, the rdp's must add up tp 100%

If you're unhappy in marriage examine the power distribution between you and your spouse, and then grow up so it might be easier to get along with you.
