What Does It Mean to Be Humble?

1 Peter 5 (KJV)
6 Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time:
7 Casting all your care upon him; for he careth for you.

What does Peter mean? How can we be humble? How can we put away pride?

The answer to me can be found in our priorities. What or whom do we put first? Do we seek wealth or fame at the expense of those we love? Do we insist on being right rather than embracing others? Do we consider ourselves better than another? Do we seek to protect ourselves from those who would harm us, or do we seek to avenge those wrongs and return harm for harm?
