How do you make friends?
Think about the friends closest to you, why do you trust them?
Are you influenced by your friends? How?
Have you ever gotten into trouble because you went along with something a friend did?
Proverbs 13:20 NIV
[20] Walk with the wise and become wise, for a companion of fools suffers harm.
Think about the kind of person you want to be. Do your friends match that description? Chances are, how they act, and the choices they make will influence you. What do you want your reputation to be?
