Proverbs 13:20
"He who walks with the wise grows wise, but a companion of fools suffers harm."
You are the company you keep.
Though you may be wise, foolish friends will eventually destroy you. Though you may be foolish, wise friends will show and teach you success. This is an easy way to prosper.
What a simple rule for wisdom and life! Get rid of foolish friends, and choose the wise for friends. You will grow in wisdom and avoid much trouble in life. Good athletes use superior competition to bring out their best, even if it means frequent training losses.
Watch the company you keep.
Be blessed!
