(1) live to please God alone,
(2) not care about your own reputation (what others think of you),
(3) not be concerned about how your prayers are going to be answered,
(4) rejoice when someone else loves the Lord more than you do,
(5) never look down on someone who might not be as advanced as you spiritually,
Actually, (1) is all I need to have put down as it covers the rest.
