Knowing others is intelligence; knowing yourself is true wisdom.
The source of human maturity is wisdom: Those who know best how to achieve and maintain high-EQ make wise decisions. To be wiser both individually and institutionally is necessary for everyone, especially for leaders. The wisdom you need is to find value in your experience - Wisdom comes from the experience of intelligence whether it be exterior or interior. You will do self-reflection via direct experience; you can also learn from others’ experience, but always do your best for validating, not just blindly believing; and don't be afraid to take an active roll on creating that experience, so you can gain more wisdom and remember the more foolish it looks, the more there may be to learn. Decide what you are willing to put up with and let it rip and let the big U fill in the pieces to progress the story while you just make changes to the character you choose to be. To achieve wisdom, emotion has to merge with rational thought. The emotion of being in a particular situation is somehow stronger than witnessing someone else going through it though we can learn from both. Empathy as one of the ingredients in wisdom is an important factor if we are to learn from the experience of others. There're many kinds of smartness or multidimensional intelligence, besides conventionally known IQ and EQ, a wise mind is also good at SQ - Strategy Quotient; CQ - Creativity Quotient; PQ - Paradox Quotient, and more.
True wisdom comes from taming these behaviors in one’s life: Envy, hatred, greed, self-indulgence, selfishness, back-biting, rumor-mongering, placing boundaries around emotions and understating cause and effect. Wisdom is driven by a central logic that can be considered value judgment, intellectual maturity, universal love, thoughtfulness - considers consequences of one’s actions in regards to others. Wisdom is built around boundaries and definite measures of behavior as it relates to entire environmental systems that allow continuation. Wisdom then comes down to self-worth. Do to others as you wish them to do to you. But it is behavior that takes into account the entire ecosystem which includes one’s behavior. True wisdom is how you make sound judgment and positive influence to make this world a better place by fitting into a larger system of continuity. True wisdom is to bridge the old with new, and mind the gaps in such transformation.
