Doing something positive toward another person is a practical approach to feeling good about yourself. (Barbara Johnson, author and speaker)

Somehow self-centered people can relate to other people only as the relationship seems to benefit them. They appear to feel good about themselves only at the expense of someone else. How sad that kind of life must be. To really feel good about yourself, try doing good for others. It will improve how both of you feel about yourselves.

Whoever refreshes others will be refreshed. (Proverbs 11:25) In humility value others above yourselves. (Philippians 2:3)
