Philippians 3:12-14 is a wonderful passage for leaders to memorize.
Not that I have already attained, or am already perfected; but I press on, that I may lay hold of that for which Christ Jesus has also laid hold of me. Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal for the prize of the upward call of God in Christ Jesus.
Write out the passage. Make an effort to memorize it. Let it remind you to press toward the mark.
