1. Look for people who talk negatively about you
Friends may have constructive criticism for you, but their ultimate goal is to help you. An enemy will use destructive talk with the sole purpose of making you feel worse or bringing you down.
2. Notice who gossips about you
People who gossip behind your back, spreading malicious rumors or letting out your darkest secrets, are not your friends. If you find someone is gossiping about you, they're probably your enemy
3. Watch for people who try to block your success.
Many times, your enemies will work to take credit for what you do, particularly in a work or school environment. They may also try to stop you from succeeding by subtly sabotaging your work with your boss or your teacher. These people are definitely not your friends
4. Pay attention to the person's body language.
A person who doesn't like you will likely lean away from you, as well as turn their body away from you in conversation. They may also cross their arms or legs as a defense against you.
