Don't be selfish, don't try to impress others. Be humble, thinking of others as better than yourself. Don't look out only for your own interests, but take an interest in others too.
In everything we do, we must not do it because of our own selfish desires or simply to impress others. In every thing we do, we must do it to glorify God's name. We must also keep ourselves humble so that temptation would not lead us to desire worldly goals and success. Hence, we will not be hindered in our way as we walk on the path of God's holiness.
