Intelligence =
Discipline + Dedication + Motivation + Drive + Delayed Gratification + Sacrifice + Strict & Encouraging Parents/Family + Societal Influence (example. Asian cultures) + Consistent Good Decision Making + Good Emotional Management + Self Reflection & Constant Self Improvement
- Bad Influences - Bad Habits & - Wrong Choices
Essentially, Nature + Nurture determines +80% of an individuals intelligence, values, morals, perception & success...
Luck & Genes too but only ~ 20%
Most Asian individuals (&/or 'Foreigner/Immigrants' ) were raised differently than many people in the US/UK/EU, with strict parents, who from a young age engrained discipline into them, the importance of constantly learning for life, getting excellent grades by excessively studying, attending school daily so not to get left behind & the importance of making good choices are.. to your future & /or your success
Each generations is raised this way, everyone in their neighborhood is raised this way, their city, their country etcetera..
Highly discipled & hard working w/ little or no time for "fun"...
Nature + Nurture
