WISDOM
Wisdom is key. Intelligence is a tool. Wisdom is the application of the tool.
My sister is one of those people with exceptional intellegence (Rediculously high IQ [top 0.1%,]) but she utterly lacks wisdom. While she can solve problems the "average man" cannot phathom and entertain enigma and paradox that would send the "run-of-the-mill genius" into shivering, babbling fits of madness, her life is a complete disaster. I mean, shockingly so.
Remember, a wise, uneducated man with average intelligence is still a wise man.
A learned, intelligent man who lacks wisdom is still a fool.
Seek wisdom, anon. Seek wisdom.
