Write down the names of 5-10 people you look up to most...it doesn't necessarily have to be people you know personally.
Under each name, write the top 3 characteristics you most admire in his or her personality.
Look at the traits once you are through -- know that you wouldn't admire these things if there weren't seeds of them in yourself.
Now read Philippians 1:27-2:4. Think about how you can use those traits that God has so generously blessed you with in order to strengthen the unity of the body of Christ.
