Only those who have the capacity to really listen and hear…. gain wisdom.
This is why the human ego is a pesky critter. It gets in the way of growth, maturity and wisdom.
The human ego is a like a road block. Any many people stop growing emotionally in the childhood and teenage years. They don’t progress along the emotional development, maturity path.
Wisdom is only gained, through the capacity to listen, to be willing to be wrong, to seek to learn and have the willingness to change.
Basically, wisdom is only gained through the capacity for humility.
Humility being the opposite of a unhealthy, immature ego.
