Do nothing 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 the others.
Am I able to say, from my heart of hearts, that I value others above myself? Do I put others first? There are many, many people that I can truly make that statement about, however, there are more that I would not. And the truth is humbling, embarrassing, and eye opening.
