Do you wish to become wise? Then you must walk with people who, by their words and their presence make you wiser. And to the best of your ability you must avoid those people who don’t. That means you must choose wise friends and mentors.
The next best thing to being wise oneself is to live in a circle of those who are. C.S. Lewis
A wise man will hear and increase learning, and a man of understanding will attain wise counsel. Proverbs 1:5
The one who walks with the wise will become wise, but a companion of fools will suffer harm. Proverbs 13:20
