Have you been in a place where you were stranded, or in a difficult situation that was out of your control? You were wishing for someone to show up and save the day. Instead, all you saw were busy people that just kept staying busy with their life and not even noticing you and your need. How did that make you feel?
Important? Loved? Cared for? Special?
Do noting out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of others.
